Fraser Cormack 5e5115bbd0 [MemCpyOpt] Fix a variety of scalable-type crashes ... This patch fixes a variety of crashes resulting from the `MemCpyOptPass` casting `TypeSize` to a constant integer, whether implicitly or explicitly. Since the `MemsetRanges` requires a constant size to work, all but one of the fixes in this patch simply involve skipping the various optimizations for scalable types as cleanly as possible. The optimization of `byval` parameters, however, has been updated to work on scalable types in theory. In practice, this optimization is only valid when the length of the `memcpy` is known to be larger than the scalable type size, which is currently never the case. This could perhaps be done in the future using the `vscale_range` attribute. Some implicit casts have been left as they were, under the knowledge they are only called on aggregate types. These should never be scalably-sized. Reviewed By: nikic, tra Differential Revision: https://reviews.llvm.org/D109329 (cherry-picked from commit 7fb66d4)		2021-09-09 16:21:27 -07:00
