fix ret amount to match enter
Whoops, enter and ret take different arguments. Back out last change.
Add -debug flag and $debug_print variable
add pre-SSA BB id to CFG
Fix up instruction code generation to account for constant propagation (and debugging)
Forgot I already had a $debug global. use that one.
Add basic block map to make fixing branch targets easier
Improve SSA move conversion
More branch target fixes (don't worry about fixing targets when deleting instructions)
Replace moves to SSA variables with loads
Many debug print lines
