Add a build flag to make -Werror optional and let the build continue
even in the presence of warnings.
This option is very useful for anyone compiling with a different
(version of the) compiler. A different (version of the) compiler may
produce a different set of warnings and a piece of code that compiles
without warnings may emit warnings with a different (version of the)
compiler.

* [x86/Linux] Implement libunwind-based unwindLazyStack
This commit implements libunwind-based unwindLazyStack for x86/Linux
in order to fix #8625.

* [x86/Linux] Fix "Bad opcode" assert in unwindLazyState
This commit suppresses "Bad opcode" assert while runing "Hello, World" example.
This commit address the following three code patterns discovered while
digging the assert failure:
- and $0x1, %al
- xor $0xff, %al
- stack protection code:
mov %gs:<off>, <reg>
cmp <off>(%esp), <reg>
mov <reg>, <off>($esp)
jne <disp32>
This commit revises LazyMachState::unwindLazyState to handle the first two patterns,
and revises compile options not to emit the third pattern.

Currently, '-DARM_SOFTFP' is added inside jit/CMakeList.txt and
vm/CMakeLists.txt, and thus the header definition might be inconsistent
across each componenet.
This inconsistency results in some strange behavior discussed in #5629.
This commit tries to enforce the consistent definition of '-DARM_SOFTFP'
for every component via definiing it inside compileoptions.cmake in order
to fix #5629.

Add fwrapv compile option

Some architectures including ARM assumes that plain char is
unsigned unlike x64.
Because CoreCLR has been assuming char is signed, we need to
explictly tell the toolchain the signedness of char type.

1. Update arm64 toolset to latest.
2. Link against ucrt.
3. Fix tls offsets which have changed due to updated toolset
4. Fix source code in decimal.cpp to avoid integer overflow. Result of signed integer overlfow is undefined in C++.
5. Enable build of sos which can be loaded in arm64 windbg
6. Add nop to empty assembly marker methods as new toolset generates invalid .pdata for them.

Currently only enabled for arm64
