Utf8String is an experimental type that is string-like (heap-allocated, immutable, variable-length, null-terminated) but whose inner representation is UTF-8, not UTF-16.
This is a skeleton implementation of the basic API shape. The ecosystem of APIs has not yet been built around it. All Utf8String-related code is currently surrounded by ifdefs to allow easy identification and removal from release branches.

Eliminate `FEATURE_UNIX_AMD64_STRUCT_PASSING` and replace it with `UNIX_AMD64_ABI` when used alone. Both are currently defined; it is highly unlikely the latter will work alone; and it significantly clutters up the code, especially the JIT.
Also, fix the altjit support (now `UNIX_AMD64_ABI_ITF`) to *not* call `ClassifyEightBytes` if the struct is too large. Otherwise it asserts.

This is needed so that we can turn default interfaces off in release branches.
I can't find a central location where the PRERELEASE flag could be defined because native and managed builds seem to be completely disconnected.
To limit the risk of only flipping the flag in one build type, I'm adding a test that verifies being able to load an interface with default methods matches what RuntimeFeature says.

Linux and Windows arm64 are using the regular C/C++ thread local statics. This change unifies the remaining Windows architectures to be on the same plan.

* Introduce FEATURE_GDBJIT_SYMTAB
This commit adds new feature FEATURE_GDBJIT_SYMTAB. When it's set
ELF file with symtab section will be generated for all JITed methods.
It helps lldb and gdb correctly unwind frames of JITed methods as they
can use assembly language inspection to determine location of saved
registers on stack.
* gdbjit symtab feature: use different symbols for each function in JITed code
|
|
* [GDBJIT] Specify C# language in DWARF debug information
To correctly support C# language in lldb DWARF debug information
should contain correct information about language.
Now we use 0x9e57 constant for specify C# language.
* [GDBJIT] Introduce FEATURE_GDBJIT_LANGID_CS
If this feature is set gdbjit will use 0x9e57 as c# lang id,
otherwise it will use DW_LANG_C89.

BitScanForward64

PR
3. Fix the Unix build

* Remove a number of things from gcenv.base.h that are not used
* Remove a linker workaround now that we are not linking a standalone GC into the runtime
* Remove dead code, make the lack of GC_PROFILING for standalone gc not break profiling on the non-standalone build
* Code review feedback - use add_library_clr and other cmake-related fixes
* Fix include indentation
* Remove some extraneous parameters to cmake functions (cmake is remarkably lenient...)

* Fix Release build error
* Add flags in EEConfig

Implement out of context stack unwinder
Decode the eh frame info found in the in-memory module image
and pass it back to the remote libunwind8 to do the unwind.
Added remote-unwind.cpp for all the out of context unwind code.
Added an all managed threads option -all the "clrstack" (sos ClrStack).
The IDebugDataTarget4 feature needs to be enabled for OS X.
Add libunwind license notice to third party notices file.

This makes tiered compilation work properly with profiler ReJIT, and positions the runtime to integrate other versioning related features together in the future. See the newly added code-versioning design-doc in this commit for more information.

JSON. SampleProfiler that globally suspends the runtime every 1ms to walk stacks and write them to the EventPipe.

Tiered compilation is a new feature we are experimenting with that aims to improve startup times. Initially we jit methods non-optimized, then switch to an optimized version once the method has been called a number of times. More details about the current feature operation are in the comments of TieredCompilation.cpp.
This is only the first step in a longer process building the feature. The primary goal for now is to avoid regressing any runtime behavior in the shipping configuration in which the complus variable is OFF, while putting enough code in place that we can measure performance in the daily builds and make incremental progress visible to collaborators and reviewers. The design of the TieredCompilationManager is likely to change substantively, and the call counter may also change.

Enable Windows hosted, Linux target amd64 altjit
With this change, we build a JIT that runs on Windows amd64
and targets Linux amd64, as an altjit named linuxnonjit.dll.
This is useful for debugging, or generating asm code or diffs.
You can even easily create Windows/non-Windows asm diffs
(either to compare the asm, or compare the generated code size).
For this to work, the JIT-EE interface method
getSystemVAmd64PassStructInRegisterDescriptor() was changed
to always be built in, by defining `FEATURE_UNIX_AMD64_STRUCT_PASSING_ITF`
in all AMD64 builds. The `_ITF` suffix indicates that this is
functionality specific to implementing the JIT-EE interface
contract. There were many places in the VM that used this
interchangeably with `FEATURE_UNIX_AMD64_STRUCT_PASSING`. Now,
`FEATURE_UNIX_AMD64_STRUCT_PASSING` means code in the VM needed
to implement this feature, but not required to implement the
JIT-EE interface contract. In particular, MethodTables compute
and cache the "eightbyte" info of structs when loading a type.
This is not done when only `FEATURE_UNIX_AMD64_STRUCT_PASSING_ITF`
is set, to avoid altering MethodTable behavior on non-Unix
AMD64 builds. Instead, if `getSystemVAmd64PassStructInRegisterDescriptor()`
is called on a non-Unix build (by the altjit), the `ClassifyEightBytes()`
function is called, and nothing is cached. Hopefully (though it was
hard for me to guarantee by observation), calling `ClassifyEightBytes()`
does not have any side effects on MethodTables. It doesn't really matter,
since if called for altjit, we don't care too much about running.
The previously used `PLATFORM_UNIX` define is now insufficient.
I introduced the `#define` macros `_HOST_UNIX_` to indicate the
JIT being built will run on Unix, and `_TARGET_UNIX_` to indicate
the JIT is generating code targeting Unix. Some things were
converted to use the `UNIX_AMD64_ABI` define, which makes more
sense.
