ae3ffba466 Fix a major regression last night that prevented us from producing [mem] op= reg 
operations.

The body of the if is less indented but unmodified in this patch.

2a4e508281 Codegen this: 
int %foo(int %X) {
        %T = add int %X, 13
        %S = mul int %T, 3
        ret int %S
}

as this:

        mov %ECX, DWORD PTR [%ESP + 4]
        lea %EAX, DWORD PTR [%ECX + 2*%ECX + 39]
        ret

instead of this:

        mov %ECX, DWORD PTR [%ESP + 4]
        mov %EAX, %ECX
        add %EAX, 13
        imul %EAX, %EAX, 3
        ret

Do not fold a load into an operation if it will induce a cycle in the DAG.

Repeat after me: dAg.

b352fa5853 Move code out of indentation one level to make it easier to read. 
Disable the xform for < > cases.  It turns out that the following is being
miscompiled:

bool %test(sbyte %S) {
        %T = cast sbyte %S to uint
        %V = setgt uint %T, 255
        ret bool %V
}

cb1aa8d772 Do not fold a load into a comparison that is used by more than one place. 
The comparison will probably be folded, so this is not ok to do.
This fixed 197.parser.

fold it into its single user if possible.

da2ce11407 * Adjust to changes in TargetLowering interfaces. 
* Remove custom promotion for bool and byte select ops.  Legalize now
  promotes them for us.
* Allow folding ConstantPoolIndexes into EXTLOAD's, useful for float immediates.
* Declare which operations are not supported better.
* Add some hacky code for TRUNCSTORE to pretend that we have truncstore
  for i16 types.  This is useful for testing promotion code because I can
  just remove 16-bit registers all together and verify that programs work.

55ba8fba75 Revamp supported ops. Instead of just being supported or not, we now keep 
track of how to deal with it, and provide the target with a hook that they
can use to legalize arbitrary operations in arbitrary ways.

Implement custom lowering for a couple of ops, implement promotion for select
operations (which x86 needs).
