New Revision: 123418

URL: http://llvm.org/viewvc/llvm-project?rev=123418&view=rev
Log:
Rather than doing early instcombine, try doing early CSE instead.  This should still handle
most important simplifications, as well as resolving phase ordering issues where instcombine
would inhibit important CSE'ing opportunities, for instance on BitBench/drop3.
