Chris Lattner b686af053e 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130018 91177308-0d34-0410-b5e6-96231b3b80d8		2011-04-22 21:59:37 +00:00
