487da75338 Handle multiple exit blocks correctly. 
Restore string variable cache.
Resurrect code to use formatted printing instead of PrintVal
but leave it turned off for now.

a8ed40026f Massive hacks to try to fix subtle logic bugs. I think it's all working now, 
at least what used to.  I should disable method exit code completely because
it's broken (doesn't insert just post dominating values)

0ba9c3d61b 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).

c83118d53f 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.

abed788cd9 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.
