Nate Begeman bb01d4f272 Remove BRTWOWAY*
Make the PPC backend not dependent on BRTWOWAY_CC and make the branch
selector smarter about the code it generates, fixing a case in the
readme.

more target independant, generate better code, and be less conservative.

Evan Cheng 3df447d354 For each loop, keep track of all the IV expressions inserted indexed by
stride. For a set of uses of the IV of a stride which is a multiple
of another stride, do not insert a new IV expression. Rather, reuse the
previous IV and rewrite the uses as uses of IV expression multiplied by
the factor.

e.g.
x = 0 ...; x ++
y = 0 ...; y += 4
then use of y can be rewritten as use of 4*x for x86.

Chris Lattner 6d6084fd04 Teach the strip pass to strip type names in addition to value names. This

Andrew Lenharth 3196422df0 Handle one offset with growth case seen in povray. Namely, if we have an offset,
and the offset lands at a field boundary in the old type, construct a new type,
copying the fields masked by the offset from the old type, and unify with that.
