-       movl %edi, %ecx
-       andl $2, %ecx
-       cmpl $0, %ecx

There are a couple of dagiselemitter deficiencies that this exposes, they will
be handled later.

actually *removes* one of the operands, instead of just assigning both operands
the same register.  This make reasoning about instructions unnecessarily complex,
because you need to know if you are before or after register allocation to match
up operand #'s with the target description file.

Changing this also gets rid of a bunch of hacky code in various places.

This patch also includes changes to fold loads into cmp/test instructions in
the X86 backend, along with a significant simplification to the X86 spill
folding code.
