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).

87875dac89 Turn select C, (X+Y), (X-Y) --> (X+(select C, Y, (-Y))). This occurs in 
the 'sim' program and probably elsewhere.  In sim, it comes up for cases
like this:

#define round(x) ((x)>0.0 ? (x)+0.5 : (x)-0.5)
double G;
void T(double X) { G = round(X); }

(it uses the round macro a lot).  This changes the LLVM code from:

        %tmp.1 = setgt double %X, 0.000000e+00          ; <bool> [#uses=1]
        %tmp.4 = add double %X, 5.000000e-01            ; <double> [#uses=1]
        %tmp.6 = sub double %X, 5.000000e-01            ; <double> [#uses=1]
        %mem_tmp.0 = select bool %tmp.1, double %tmp.4, double %tmp.6
        store double %mem_tmp.0, double* %G

to:

        %tmp.1 = setgt double %X, 0.000000e+00          ; <bool> [#uses=1]
        %mem_tmp.0.p = select bool %tmp.1, double 5.000000e-01, double -5.000000e-01
        %mem_tmp.0 = add double %mem_tmp.0.p, %X
        store double %mem_tmp.0, double* %G
        ret void
