1. Move most of the constant-fixup code into machine-independent file
   InstrSelectionSupport.cpp.  It now happens in a bottom-up pass on
   each BURG tree after the original top-down selection pass on the tree.
2. Handle global values as constants (viz., constant addresses).

Generate assembly code for testcodegen.

Added several cases where a constant must be forwarded into a use.

Moved implementation of class UltraSparcInstrInfo to SparcInstrInfo.cpp.

Added virtual function to generate an instruction sequence to
load a constant into a register.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@862 91177308-0d34-0410-b5e6-96231b3b80d8

Moved implementation of class UltraSparcInstrInfo here.

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.

Separate VM instruction that generates the instructions that compute a value
from the value itself (the one causing an edge) because the latter may be
a temporary used within the instruction sequence for the VM instruction.
