Windows Support
---------------
- Add support for MSVC-compatible ``/JMC``/``/JMC-`` flag in clang-cl (supports
X86/X64/ARM/ARM64). ``/JMC`` could only be used when ``/Zi`` or ``/Z7`` is
turned on. With this addition, clang-cl can be used in Visual Studio for the
JustMyCode feature. Note, you may need to manually add ``/JMC`` as additional
compile options in the Visual Studio since it currently assumes clang-cl does not support ``/JMC``.
C Language Changes in Clang
