This also cleans up a bit of the memcpy call rewriting by sinking some irrelevant code further down and making the call-emitting code a bit more concrete. Previously, memcpy of a subvector would actually miscompile (!!!) the copy into a single vector element copy. I have no idea how this ever worked. =/ This is the memcpy half of PR14478 which we probably weren't noticing previously because it didn't actually assert. The rewrite relies on the newly refactored insert- and extractVector functions to do the heavy lifting, and those are the same as used for loads and stores which makes the test coverage a bit more meaningful here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170338 91177308-0d34-0410-b5e6-96231b3b80d8
