[ConstantFolding] Canonicalize constexpr GEPs to i8 (#89872)
This patch canonicalizes constant expression GEPs to use i8 source
element type, aka ptradd. This is the ConstantFolding equivalent of the
InstCombine canonicalization introduced in #68882.
I believe all our optimizations working on constant expression GEPs
(like GlobalOpt etc) have already been switched to work on offsets, so I
don't expect any significant fallout from this change.
This is part of:

If nonnull is already set, we currently skip setting both nonnull

These tests cases were converted using the script at
https://gist.github.com/nikic/98357b71fd67756b0f064c9517b62a34,
but there was also a need to re-run update_test_checks.py (impacting
nonnull/dereferencable attributes).
