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.
