dae87b6536 Added a break that I meant to include originally, for efficiency. Basically
it keeps it from trying to add the same node to the node set
over and over if it matches multiple given patterns.  Also in cases where there
are a lot of patterns to be matched, and it matches an early one, this
will make the script run slightly faster.  It's more there because it logically
should be, than anything else, I mean, Python is never going to be fast ;-)

69a889eb35 Fix a nasty latent bug in the legalizer that was triggered by my patch
last night, breaking crafty and twolf.  Make sure that the newly found
legal nodes are themselves not re-legalized until the next iteration.

Also, since this functionality exists now, we can reduce number of legalizer
iterations by depending on this behavior instead of having to misuse 'do
another iteration' to get the same effect.

88276b887c 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
  ret void
}

We now produce:
_foo:
        lvx v0, 0, r3
        vaddfp v0, v0, v0
        stvx v0, 0, r3
        blr

Instead of:
_foo:
        li r2, 0
        lvx v0, r2, r3
        vaddfp v0, v0, v0
        stvx v0, r2, r3
        blr

7c423b4df1 Fix pifft by correcting the case when a i64/f64 straddles O5 and memory:
we were storing into [FP+88] instead of [FP+92].
Improve codegen by emitting [FP+92], instead of emitting a copy of FP into
another GPR which wouldn't be coallesced because FP isn't register allocated.

7e1cf1c8f4 This is a script to extract nodes and edges associated with those nodes
from a dot file that is the output of DSA.  Nodes to extract
are specified by giving the name of the node seen in the graphical
representation, i.e. in the .ps if the node is specified %xyz
asking for just x, xy, or xyz will retain it in the output file.
Because it operates on substrings underspecifying may result
in additional unexpected nodes.  Be as specific as possible.
Obviously, however, if you ask for %xyz and there is a
getelementptr of %xyz you will get both nodes.  Some manual
editing may still be necessary because of this, but this script
can pare down 10,000 line files to 20 line files, making like easier.
