Dan or Evan, please review.

Remove code that pad number of bytes to pop for X86_FastCall CC. The code doesn't do the "aligning" for Cygwin, Mingw, and Windows. But aligning it on Darwin and Linux breaks gcc compatibility. That ruled out all the platforms we support!

No functional change (and no FE change to generate them).

HandlePHINodesInSuccessorBlocks that works FastISel-style. This
allows PHI nodes to be updated correctly while using FastISel.

This also involves some code reorganization; ValueMap and
MBBMap are now members of the FastISel class, so they needn't
be passed around explicitly anymore. Also, SelectInstructions
is changed to SelectInstruction, and only does one instruction
at a time.

Fix capitalization in #include of FastISel.h.  This unbreaks the build on case-sensitive filesystems.

Let tblgen only generate fastisel routines, not the class definition. This makes it easier for targets to define its own fastisel class.

Change getBinaryCodeForInstr prototype. First operand MachineInstr& should be const. Make corresponding changes.

instructions in CellSPU as "Expand" so that they won't be generated. I added a
"FIXME" so that this hack can be addressed and reverted once ISD::ROTR is
supported in the .td files.

Dale, Could you please review this?

For now, can't mark XOR64rr isAsCheapAsAMove. It's technically correct. But various passes cannot handle remating these.

Transform (x << (y&31)) -> (x << y). This takes advantage of the fact x86 shift instructions 2nd operand (shift count) is limited to 0 to 31 (or 63 in the x86-64 case).
