922d314e8f Instruction scheduling itinerary for Intel Atom. 
Adds an instruction itinerary to all x86 instructions, giving each a default latency of 1, using the InstrItinClass IIC_DEFAULT.

Sets specific latencies for Atom for the instructions in files X86InstrCMovSetCC.td, X86InstrArithmetic.td, X86InstrControl.td, and X86InstrShiftRotate.td. The Atom latencies for the remainder of the x86 instructions will be set in subsequent patches.

Adds a test to verify that the scheduler is working.

Also changes the scheduling preference to "Hybrid" for i386 Atom, while leaving x86_64 as ILP.

Patch by Preston Gurd!

6904f05e60 Triple::MinGW64 is deprecated and removed. We can use Triple::MinGW32 generally. 
No one uses *-mingw64. mingw-w64 is represented as {i686|x86_64}-w64-mingw32. In llvm side, i686 and x64 can be treated as similar way.

cf6b739d3d Unbreak Win64 CC. Step one: honour register save area, fix some alignment and provide a different set of call-clobberred registers.

bccf4b3050 PR3739, part 2: Use an explicit store to spill XMM registers. (Previously, 
the code tried to use "push", which doesn't exist for XMM registers.)
