Chris Lattner d9c0db9bd7 Recommit the fix for rdar://9289512 with a couple tweaks to ... fix bugs exposed by the gcc dejagnu testsuite: 1. The load may actually be used by a dead instruction, which would cause an assert. 2. The load may not be used by the current chain of instructions, and we could move it past a side-effecting instruction. Change how we process uses to define the problem away. llvm-svn: 130018		2011-04-22 21:59:37 +00:00
