Nick Lewycky 8899d5c6fb Teach globalopt to not nuke all stores to globals. Keep them around of they ... might be deliberate "one time" leaks, so that leak checkers can find them. This is a reapply of r160602 with the fix that this time I'm committing the code I thought I was committing last time; the I->eraseFromParent() goes *after* the break out of the loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160664 91177308-0d34-0410-b5e6-96231b3b80d8		2012-07-24 07:21:08 +00:00
