a0db1c9a0e Only print values live at BB or method exit, and insert loads at each 
BB exit to read and print values stored in that BB.   Note that only
these stored values are live at method exit!.  Also, print messages at
method entry and exit.

b2ac1e76b4 Trace code should always be exported just before code generation; 
this is not a debugging option.  But we can export it as assembly
instead of bytecode if -debugtrace is specified.

Resurrect code to use formatted printing instead of PrintVal
but leave it turned off for now.

a0a8b5bc26 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)

6c697526bf 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).

af854b59c2 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.
