The code added in #116191 that updated the lanemasks for rematerialized
values checked if `DefMI`'s destination register had a subreg index.
This seems to have missed the following case:

Hi @tru, these are all bugfixes for things that would somehow lead to a
compilation failure when targeting AArch64 SME instructions. I don't see any

f314e12 uses `requiresSaveVG` which was introduced in 334a366ba792, which is
also missing from the release/19.x branch.
I figured it made sense to cherry-pick that one as well.

Thanks for making this change! The Clang/driver behaviour looks correct to me
now. The patch is a lot smaller than the patches that went into main, so
hopefully this can still make it into LLVM 19!

Thanks for checking. The only failures I would have expected are from lit
tests, but the PR was merged on Monday and I've not seen any buildbot failures,
so I believe it is safe.

Looks pretty low-risk to me and would be nice to get into the release if we can.
