Nikita Popov 6f7e5c0f1a Reapply [SimplifyCFG][LICM] Preserve nonnull, range and align metadata when speculating 
This exposed a miscompile in GVN, which was fixed by D148129.

-----

After D141386, violation of nonnull, range and align metadata
results in poison rather than immediate undefined behavior,
which means that these are now safe to retain when speculating.
We only need to remove UB-implying metadata like noundef.

This is done by adding a dropUBImplyingAttrsAndMetadata() helper,
which lists the metadata which is known safe to retain on speculation.
