22bb31103d Factor out the predicate check code from DAGISelEmitter.cpp 
and use it in FastISelEmitter.cpp, and make FastISel
subtarget aware. Among other things, this lets it work
properly on x86 targets that don't have SSE, where it
successfully selects x87 instructions.

1887c1c2f9 Fix a number of byval / memcpy / memset related codegen issues. 
1. x86-64 byval alignment should be max of 8 and alignment of type. Previously the code was not doing what the commit message was saying.
2. Do not use byte repeat move and store operations. These are slow.
