[cfe-commits] [PATCH] Implement va_arg alignment in clang on ARM

[Jim (Ningjie) Chen]

Hello. First-time contributor :)

This patch implements alignment for long long types in va_arg on ARM AAPCS.
Without alignment, sqlite breaks on ARM because it uses 64-bit types extensively in vaarg calls (printf).

I also included a test if that is needed.

Thanks!
Jim
