fe177d219a bug 122:

  Constant.

9bcf258cc3 Make sure to emit the immediate byte for instructions like: 
shrd [mem], reg, imm

36bf6aa37c * Use LI(S) to copy constants into registers intead of ADDI(S) as the latter is 
a funky way to "use" R0 for a 0-valued operand
* Add IMPLICIT_DEFs for incoming function arguments via registers to help the
  register allocator not clobber those registers
* Implement comparisons with longs
* Teach emitSelectOperation() to fold the SetCC operation
