Summary: Re-lands r328386 and r328443, reverting r328482. Incorporates fixes from @mstorsjo in D44876 (thanks!) so that small parameters in i8 and i16 do not end up in the SysV register parameters (EDI, ESI, etc). I added tests for how we receive small parameters, since that is the important part. It's always safe to store more bytes than will be read, but the assumptions you make when loading them are what really matter. I also tested this by self-hosting clang and it passed tests on win64.
