7fe27874be 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).

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.

f43e3366ef 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.
