Summary: This change is part of step five in the series of changes to remove alignment argument from memcpy/memmove/memset in favour of alignment attributes. In particular, this changes the MemCpyOpt pass to cease using: 1) The old getAlignment() API of MemoryIntrinsic in favour of getting source & dest specific alignments through the new API. 2) The old IRBuilder CreateMemCpy/CreateMemMove single-alignment APIs in favour of the new API that allows setting source and destination alignments independently. We also add a few tests to fill gaps in the testing of this pass. Steps: Step 1) Remove alignment parameter and create alignment parameter attributes for memcpy/memmove/memset. ( rL322965, rC322964, rL322963 ) Step 2) Expand the IRBuilder API to allow creation of memcpy/memmove with differing source and dest alignments. ( rL323597 ) Step 3) Update Clang to use the new IRBuilder API. ( rC323617 ) Step 4) Update Polly to use the new IRBuilder API. ( rL323618 ) Step 5) Update LLVM passes that create memcpy/memmove calls to use the new IRBuilder API, and those that use use MemIntrinsicInst::[get|set]Alignment() to use [get|set]DestAlignment() and [get|set]SourceAlignment() instead. ( rL323886, rL323891, rL324148, rL324273, rL324278, rL324384, rL324395, rL324402, rL324626, rL324642, rL324653, rL324654, rL324773, rL324774, rL324781, rL324784, rL324955, rL324960, rL325816, rL327398, rL327421 ) Step 6) Remove the single-alignment IRBuilder API for memcpy/memmove, and the MemIntrinsicInst::[get|set]Alignment() methods.
