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).
