[PATCH] Use the MS ABI for Win32 target by default

Hi rnk,

This makes Clang use the MS ABI by default when targeting Win32.

In addition to being a sensible default, this also improves the test coverage for the MS ABI: any bot that targets Win32 will now run the tests in MS ABI mode by default.

I plan to commit this in two steps: test updates first, and functionality change second so that it can be reverted separately if needed.
