[DebugInfo][RemoveDIs] Avoid crash and output-difference in loop-rotate (#74093)
Avoid editing a range of DPValues and then remapping them. This occurs
when we try to de-duplicate dbg.values, but then re-use the same
iterator range. We can instead remap them, and then erase any
duplicates.
At the same time refactor the computation of seen-intrinsic hashes, and
account for a peculiarity of loop-rotates existing behaviour: it will
only deduplicate dbg.values that are immediately before the preheaders
branch instruction, not just any dbg.value in the preheader.
