patch for PR9027 and // rdar://11861085 Title: [PR9027] volatile struct bug: member is not loaded at -O; This is caused by last flag passed to @llvm.memcpy being false, not honoring that aggregate has at least one 'volatile' data member (even though aggregate itself has not been qualified as 'volatile'. As a result, optimization optimizes away the memcpy altogether. Patch review by John MaCall (I still need to fix up a test though). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173535 91177308-0d34-0410-b5e6-96231b3b80d8
