a2b1dbead8 It looks like physref->virtreg joining is working fine. Enable it by default 
but make virtreg->virtreg joining stay off by default

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

This fixes the jit-ls failure on 186.crafty.

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

952bbd726b This patch was contributed by Daniel Berlin! 
Speed up SCCP substantially by processing overdefined values quickly.  This
patch speeds up SCCP by about 30-40% on large testcases.
