[SROA] Support load-only promotion with dynamic offset loads (#135609)

If we do load-only promotion, it is okay if we leave some loads alone.
We only need to know all stores that affect a specific location.

As such, we can handle loads with unknown offset via the "escaped
read-only" code path.

This is something we already support in LICM load-only promotion, but
doing this in SROA is much better from a phase ordering perspective.

Fixes https://github.com/llvm/llvm-project/issues/134513.
