These changes are ported from desktop CLR.

This change is to pass the flag LOCALE_ALLOW_NEUTRAL_NAMES to the OS API to allow mapping
LCID to/from culture names.

we have some optimization to check if we can perform the string search as ordinal
operation instead of lingustic operation. we used to check if the string is Ascii
which check if all chars in the string are in range 0~7F.
This check was not enough because in Linux, ICU do some special handling for some
characters in the Ascii range. so we need to avoid calling the ordinal operation
when encountering such chracters.
The fix is to take the advantage of String.IsFastSort which do exactly what we need

This is a bit large change across VM/Zap/JIT to properly support crossgen
scenario.
1. Fix incorrect `ldr` encoding with size.
2. Enforce JIT data following JIT code per method by allocating them together.
This guarantees correct PC-relative encoding for such constant data access
without fix-up.
3. For the general fix-up data acceess, use `adrp/add` instruction pairs with fix-ups.
Two more relocations types are implemented in all sides.
4. Interface dispatch stub is now implemented which is needed for
interface call for crossgen.
I've verified hello world runs with mscorlib.ni.dll.

- Move the code into the GC info encoder, as that is its
only consumer.
- Remove contracts
- Delete dead code
- Reformat and refactor to current coding standards

Enabling LongFile Support in PAL

SuperPMI has been udpated to accommodate this change, and should no
longer crash when run using a JIT built with these changes.

- `DefaultAllocator` has been replaced with `HostAllocator` in RyuJIT, which
uses the JIT hosting interface to allocate and free memory.
- The definition of `DefaultAllocator` has been moved into its own file, as it
remains in use by the interpreter and the binder.
- `ProcessHeapAllocator` has been moved into JIT32, as that was its only
remaining user.
- `AllowZeroAllocator`'s static field has been changed to an instance field
to avoid the need to define storage for the static field in Utilcode.

The CoreCLR runtime is updated to support long file paths on Windows.
Pending updates to mscorlib.dll, the following scenarios are supported:
* Run managed apps from a long path.
* Load CoreCLR runtime and framework from a long path.
* Load user assemblies from a long path.
* Run CrossGen from a long path, with its input/output from a long path.
* Generate debug log file at a long path.
The following scenarios are not yet supported, and will be fixed in
future commits:
* Mscorlib.dll and framework assemblies are not yet long path compatible.
Note that until mscorlib.dll is fixed, most of the runtime changes can't
actually be used.
* Support on non-Windows platforms.
* Support for debugging and error reporting.
* Tools such as ilasm or ildasm.

These APIs accommodate the retrieval of config values using the JIT
interface rather than the utilcode library. All configuration options
are now initialized upon the first call to compileMethod. The values
of configuration options are available off of an ambient JitConfig
object.
This also changed `JitHost::get*ConfigValue` to use the
`EEConfig_default` policy instead of `REGUTIL_default` in order to
avoid breaking a small set of JIT config options available in release
builds that were using the former. This change is exceedingly
unlikely to adversely affect the behavior of other JIT config options
that were originally fetched using `REGUTIL_default`, since values
for these options should not be present any locations searched
by `EEConfig_default` that are not searched by
`REGUTIL_default` (namely config files).

This is the first significant step towards removing the JIT's dependence on utilcode.
This change introduces a new interface, `ICorJitHost`, that allows functionality that
would usually be provided by the OS to be overridden by the program that is hosting
the JIT. At the moment, this is limited to memory allocation and configuration value
(e.g. environment variable) access. If the JIT exports a function named `jitStartup`,
an instance of the `ICorJitHost` must be provided via that function before the first
call to `getJit`.
The VM and other implementors of the JIT interface have been updated accordingly.
Most implementors should use the common implementation of `ICorJitHost` (cleverly
named `JitHost`) in utilcode which respects the CLR's hosting policy.
Note that this change does not update RyuJIT (or any other JITs) to use any of the
functionality exposed by `ICorJitHost`; that work is left for future changes.

They are:
1. Wrappers for OS APIs which take or return PATHS
2. Fixing the usage of following Api's:
GetEnvironmentVariableW
SearchPathW
GetShortPathNameW
GetLongPathNameW
GetModuleFileName
Work remaining:
Remove fixed size buffers in the VM

Added a SOS DAC interface (ISOSDacInterface4::GetClrNotification) to get the exception
notification arguments instead of using the GetLastExceptionInformation function from the lldb
sosplugin that depends on coreclr symbols being present.
On the coreclr side, the clr notification arguments are saved in a global variable that is DAC
accessible. A critical section was added to protect this global variable while the special
exception is raised.
Setting the internal COMPlus_DebugBreakOnAssert environment variable causes 3 or 4 breaks in
the debugger with no reason. It was breaking in the function that was determining whether it
should break. I was using COMPlus_BreakOnEELoad=2 to break after coreclr was loaded and initialized
to set managed breakpoints and on a debug build it generates an assert (on release just a DebugBreak).

When mscorlib is missing, crossgen reports a "file not found" error,
without indicating which file is missing. This makes it hard to discover
the actual error. This commit improves error reporting in such cases.

WaitForSingleObject was calling itself instead of delegating to

29ce4f6 worked around an issue where we were exporting C++ operators
which caused some problems on OSX in some interop cases (see
dotnet/coreclr#946 and dotnet/coreclr#943 for more details).
With dotnet/coreclr#1065 we no longer export all symbols from libcoreclr
so these additional attributes are redudent and they cause issues when
trying to build with clang 3.7. This commit removes them.
I verified that the sample AppKit app continues to work even with these
changes.

The JIT is not expected to make assumption about format of raw signatures to parse them.
Instead, it should depend on JIT-EE interface for parsing. This invariant was violates in
couple of places related to debug COMPlus_ method filters that caused them to crash under CoreRT.
Fixed the filters to use the proper abstraction instead.

Some files have their contents ifdefed out because some CLR features
(remoting, CAS, fusion etc.) are not present (and they'll probably never
be) in CoreCLR. A few others are DAC, CrossGen or arch specific so they
have been moved to the appropiate file lists.

This pulls out resource string handling out of mscorrc into top level.
The scripts (awk) are now parameterized to generate a unique string table for the
given name.
Added resourcestring.cpp to create an API "LoadResourceString".
Added a few macros into resourcestring.h, which are used for definition/uses of
the string table.

This change improves performance of CoreCLR with Server GC enabled by
about 30% according to ASP.NET benchmarks on Linux. The table below shows
number of requests per second that an ASP.NET benchmark could handle on my
machine before and after the change.
Pipeline Before After Improvement
16 230K Req/sec 305K Req/sec 33%
256 240K Req/sec 340K Req/sec 42%
The problem was that with Server GC enabled, the GC initialization code was
reserving a large chunck (about 18GB on my machine) of virtual address
space during runtime initialization. Unfortunately, due to implementation
details of MM on Linux, GC memory was located next to the location of
libcoreclr. As a result, the runtime could not allocate memory for JIT'ed
code close to the coreclr library. Because of that the JIT'ed code had to
use jump stubs to call functions from the runtime (which can become very
expensive, for example, for write barriers).
This change fixes this issue by implementing a simple allocator that tries
to reserve (during process startup) a chuck of virtual memory that is
located near the coreclr library (within 2GB range) that can be later used
for JIT'ed code.
