New Revision: 163968

URL: http://llvm.org/viewvc/llvm-project?rev=163968&view=rev
Log:
Disable new sroa now that all buildbots have tested it.

What we have so far:
- Some clang test failures (these were known already)

- Perf results are mixed, some big regressions
  http://llvm.org/perf/db_default/v4/nts/3844
  http://llvm.org/perf/db_default/v4/nts/3845

  bullet suffers a lot. matmul is interesting: slower scalar code, faster with -vectorize.

- Some dragonegg selfhost bots crash in SROA during selfhost now
