576e46fc67 asmprinter done, added crucial missing step

967abf37c5 Use the AsmPrinter for global variable init printing. This eliminates a 
bunch of code and causes V8 to start using the fancy .asciz directive that
the sun assembler supports.

change except for fewer .section directives emitted

a07da92624 Use the new predicate support that Evan Cheng added to remove some code 
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
