Added field noResults to Instruction.
...
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.

* Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead.

This is a workaround for lack of optional flag operand (return void is not
lowered so it does not have a flag operand.)

Fix a couple of the FIXMEs, thanks to suggestion from Chris. This allows
...
us to load and store vectors directly at a pointer (offset of zero) by
using r0 as the base register. This also requires some asm printer work
to satisfy the darwin assembler.
For
void %foo(<4 x float> * %a) {
entry:
%tmp1 = load <4 x float> * %a;
%tmp2 = add <4 x float> %tmp1, %tmp1
store <4 x float> %tmp2, <4 x float> *%a

We now produce:
_foo:

stvx v0, 0, r3

...
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
