MSVC doesn't support passing by-value parameters with alignment of 16-bytes or higher apparantly. What is deeply confusing is that it seems to *sometimes* (but not always) apply this to any type whose alignment is set using __declspec(align(...)). This caused lots of errors when we switch SmallVector over to use the automatically aligned character array utilities as they used __declspec(align(...)) heavily. As a pretty horrible but effective work-around, we instead cherry pick the smallest alignment sizes with specific types that happen to have the correct alignment, and then fall back to the attribute solution past them. This should resolve the MSVC build errors folks have been hitting. Sorry for that. In good news, it will do this without introducing other UB I hope. =] Thanks to Timur Iskhodzhanov for helping me test this! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162549 91177308-0d34-0410-b5e6-96231b3b80d8
