Saleem Abdulrasool 29149d5cb7 Basic: support PreserveMost and PreserveAll on Windows ARM
Do not ignore these calling conventions on Windows ARM.  They are used
by the swift runtime for certain calls.

Rafael Espindola 922f2aa9b2 Bring r325915 back.
The tests that failed on a windows host have been fixed.

Original message:

Start setting dso_local for COFF.

With this there are still some GVs where we don't set dso_local
because setGVProperties is never called. I intend to fix that in
followup commits. This is just the bare minimum to teach
shouldAssumeDSOLocal what it should do for COFF.

This reverts commit r325915.

It will take some time to fix the failures on a windows host.

Saleem Abdulrasool 4d321336d0 Basic: support Preserve{Most,All} CC on Windows
Add support for the `preserve_mostcc` and `preserve_allcc` on Windows
x86_64 and AArch64.  This is used by Swift.

Roman Levenstein 35aa5cecf2 Add attributes for preserve_mostcc/preserve_allcc calling conventions to the C/C++ front-end
Till now, preserve_mostcc/preserve_allcc calling convention attributes were only
available at the LLVM IR level. This patch adds attributes for
preserve_mostcc/preserve_allcc calling conventions to the C/C++ front-end.

The code was mostly written by Juergen Ributzka.
I just added support for the AArch64 target and tests.
