Evan Cheng d7824e208a Turn a 2-address instruction into a 3-address one when it's profitable even if the two-address operand is killed. ...

e.g.
%reg1024<def> = MOV r1
%reg1025<def> = ADD %reg1024, %reg1026
r0            = MOV %reg1025

If it's not possible / profitable to commute ADD, then turning ADD into a LEA saves a copy.
