Provide InstCombines for the following 3 cases:2013-05-06T16:55:50ZJean-Luc Dupratjduprat@apple.com2013-05-06T16:55:50Zurn:sha1:c5cf6e536598a3b1e30fce616b771d66a071a54c
A * (1 - (uitofp i1 C)) -> select C, 0, A
B * (uitofp i1 C) -> select C, B, 0
select C, 0, A + select C, B, 0 -> select C, B, A
These come up in code that has been hand-optimized from a select to a linear blend,
on platforms where that may have mattered. We want to undo such changes
with the following transform:
A*(1 - uitofp i1 C) + B*(uitofp i1 C) -> select C, A, B

Revert r164763 because it introduces new shuffles.2013-05-06T02:39:09ZNadav Rotemnrotem@apple.com2013-05-06T02:39:09Zurn:sha1:4ee312bac138a18c39353d4736eb5921532f9624

TBAA: remove !tbaa from testing cases if not used.2013-05-02T18:11:35ZManman Renmren@apple.com2013-05-02T18:11:35Zurn:sha1:436849be6acc1b8fe28d27dac9baa49129710fb3
This will make it easier to turn on struct-path aware TBAA since the metadata
format will change.

Add a test for the foldSelectICmpAndOr fix committed in r180779.2013-05-02T02:44:23ZDavid Majnemerdavid.majnemer@gmail.com2013-05-02T02:44:23Zurn:sha1:304099a56d61c2132bd101ca669003e509ca1dcb
This tests a case where C1 and C2 were the same but X and Y were different
widths.

This reverts commit r180802
There's ongoing discussion about whether this is the right place to make
this transformation. Reverting for now while we figure it out.

InstCombine: Fold more shuffles of shuffles.2013-04-30T20:43:52ZJim Grosbachgrosbach@apple.com2013-04-30T20:43:52Zurn:sha1:6548096a2e2b34e685680e6e1055b8e407c2c243
Always fold a shuffle-of-shuffle into a single shuffle when there's only one
input vector in the first place. Continue to be more conservative when there's
multiple inputs.
