efaf9be8a4 Coalesing bug fix - now checks for the same regType instead of the same
regClass since FP class has two reg Types.

fb1a6c87d6 Use node->getOpCode() instead of node->getMachineInstr()->getOpCode().
Much nicer.

e64574ce71 Major change to how defs are found when adding dependences (they
are now found as part of the initial walk of the machine code).
Also memory load/store instructions can be generated for non-memory
LLVM instructions, which wasn't handled before.  It is now.

6d35326cd5 1. Add a bottom-up pass on BURG trees that is used to fix constant operands.
Needs to be bottom up because constant values may be forward-substituted
   to their uses (i.e., into the parent in the BURG tree).
2. Move most of the constant-fixup code into machine-indepedent file
   InstrSelectionSupport.cpp.
