[PATCH] D36272: [CodeGen][x86_64] Enable 'force_align_arg_pointer' attribute at x86_64

[Anatol Pomozov via Phabricator via cfe-commits]

> Additionally, there is likely value to split the test run-line into 2, one that specifies 64 bit Windows and one that is 64 bit Linux.  The value being that they validate two different code paths (whereas 32 is the same code path).

I added a RUN for triplet '-triple x86_64-pc-win32' and tests are failing for me. I rebuilt clang without my patches and still see the same failure. It looks like the original function-attributes currently does not work with win32 triplet.
