Fixed bug - added code in pushUnconstrainedIGNodes() to check whether a node
...
is already pushed to stack by a previous call to the same method.

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.
