Owen Anderson 26c5663283 Invert and-of-or into or-of-and when doing so would allow us to clear bits of the and's mask. ... This can result in increased opportunities for store narrowing in code generation. Update a number of tests for this change. This fixes <rdar://problem/8285027>. Additionally, because this inverts the order of ors and ands, some patterns for optimizing or-of-and-of-or no longer fire in instances where they did originally. Add a simple transform which recaptures most of these opportunities: if we have an or-of-constant-or and have failed to fold away the inner or, commute the order of the two ors, to give the non-constant or a chance for simplification instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113679 91177308-0d34-0410-b5e6-96231b3b80d8		2010-09-11 05:48:06 +00:00
