it's broken (doesn't insert just post dominating values)

   each BURG tree after the original top-down selection pass on the tree.

  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.
