[llvm] r306336 - Enable vectorizer-maximize-bandwidth by default.

Agreed, r306331 caused such

  “TBAA is only for loads, stores and calls!
    %reverse = shufflevector <16 x i8> %wide.load84, …”
failures; it was reverted in r306338 and fixed in r306381. Sorry it caught r306336.

Dehao,

I think that PPC failure may have been due to r306331, and not your patch. Ayal fixed a TBAA metadata issue when recommitting his patch in r306381.

Looks like it exposes some bug in ppc, reverting the patch for now, need to have a reproducible to investigate the bug.

Log:
Enable vectorizer-maximize-bandwidth by default.

Summary:
vectorizer-maximize-bandwidth is generally useful in terms of performance. I've tested the impact of changing this to default on speccpu benchmarks on sandybridge machines. The result shows non-negative impact:

geometric mean                                   +0.29%

The regression on 453.povray seems real, but is due to secondary effects as all hot functions are bit-identical with and without the flag.

I started this patch to consult upstream opinions on this. It will be greatly appreciated if the community can help test the performance impact of this change on other architectures so that we can decided if this should be target-dependent.
