Chandler Carruth b67c9a5b02 Fix a somewhat surprising miscompile where code relying on an ABI ... alignment could lose it due to the alloca type moving down to a much smaller alignment guarantee. Now SROA will actively compute a proper alignment, factoring the target data, any explicit alignment, and the offset within the struct. This will in some cases lower the alignment requirements, but when we lower them below those of the type, we drop the alignment entirely to give freedom to the code generator to align it however is convenient. Thanks to Duncan for the lovely test case that pinned this down. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164891 91177308-0d34-0410-b5e6-96231b3b80d8		2012-09-29 10:41:21 +00:00
