out of X86ISelDAGToDAG.cpp C++ code and into tablegen code.
Among other things, using tablegen for these things makes them
friendlier to FastISel.

Tablegen can handle the case of i8 subregs on x86-32, but currently
the C++ code for that case uses MVT::Flag in a tricky way, and it
happens to schedule better in some cases. So for now, leave the
C++ code in place to handle the i8 case on x86-32.

MachineBasicBlock be passed in to SelectInstructions rather
than the FastISel constructor.

shouldn't break anything, but anyone using Sparc should watch for 
regressions.

 - UsualUnaryConversions takes an Expr *& and may modify its argument,
   this broke when it was refactored into Sema::CheckCastTypes. This
   meant that we were missing implicit casts in some places.
 - Seems pretty sad that this got through our tests.
