[PATCH] D57898: CodeGen: Fix PR40605: split constant structures generated by -ftrivial-auto-var-init when emitting initializators

Re: case when STy != Loc.getElementType() - this is already covered by other Clang tests.

I'm still unsure about the heuristic here. I believe that for auto-initialization we want to be quite aggressive with these splits (unlike for regular constant stores).
Perhaps we should do the split in the case all bytes are pattern bytes? (This is probably another use case for `forInit`)
