3495dd8b2f Fix bug exposed by this testcase: 
declare int "call_operand"      (%rtx_def*, int)        ;; Prototype for: call_operand
declare int "restore_operand"   (%rtx_def*, int)        ;; Prototype for: restore_operand

%rtx_def = type opaque
%rtx_def = type int

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.
