from the DAGToDAG cpp file.  This adds pattern support for vector and
scalar fma, which passes test/Regression/CodeGen/PowerPC/fma.ll, and
does the right thing in the presence of -disable-excess-fp-precision.

Allows us to match:
void %foo(<4 x float> * %a) {
entry:
  %tmp1 = load <4 x float> * %a;
  %tmp2 = mul <4 x float> %tmp1, %tmp1
  %tmp3 = add <4 x float> %tmp2, %tmp1
  store <4 x float> %tmp3, <4 x float> *%a
  ret void
}

As:

_foo:
        li r2, 0
        lvx v0, r2, r3
        vmaddfp v0, v0, v0, v0
        stvx v0, r2, r3
        blr

Or, with llc -disable-excess-fp-precision,

_foo:
        li r2, 0
        lvx v0, r2, r3
        vxor v1, v1, v1
        vmaddfp v1, v0, v0, v1
        vaddfp v0, v1, v0
        stvx v0, r2, r3
        blr

load.  This reduces number of worklist iterations and avoid missing optimizations
depending on folding of things into sext_inreg nodes (which aren't supported by
all targets).

in last patch.

Allow (zext (truncate)) to apply after legalize if the target supports
AND (which all do).

This compiles
short %foo() {
        %tmp.0 = load ubyte* %X         ; <ubyte> [#uses=1]
        %tmp.3 = cast ubyte %tmp.0 to short             ; <short> [#uses=1]
        ret short %tmp.3
}

to:
_foo:
        movzbl _X, %eax
        ret

instead of:

_foo:
        movzbl _X, %eax
        movzbl %al, %eax
        ret

thanks to Evan for pointing this out.
