[PATCH] D11438: Fix x86_64 fp128 calling convention

[Chih-Hung Hsieh via llvm-commits]

chh updated this revision to Diff 37952.
chh added a comment.

Sync with latest LLVM source and
add  -attr=+mmx to test cases since new default mmx is off.
Add one more parameter to getCommonSubClass and firstCommonClass,
to guarantee that returned common sub class will contain the specified simple value type.
This extra parameter is used by EmitCopyFromReg in InstrEmitter.cpp.
