[InstCombine] Move gep of phi fold into separate function
This makes sure that an early return during this fold doesn't end up skipping later gep folds.

[InstCombine] Canonicalize constant GEPs to i8 source element type (#68882)
This patch canonicalizes getelementptr instructions with constant
indices to use the `i8` source element type. This makes it easier for
optimizations to recognize that two GEPs are identical, because they
don't need to see past many different ways to express the same offset.
This is a first step towards
https://discourse.llvm.org/t/rfc-replacing-getelementptr-with-ptradd/68699.
This is limited to constant GEPs only for now, as they have a clear
canonical form, while we're not yet sure how exactly to deal with
variable indices.
The test llvm/test/Transforms/PhaseOrdering/switch_with_geps.ll gives
two representative examples of the kind of optimization improvement we
expect from this change. In the first test SimplifyCFG can now realize
that all switch branches are actually the same. In the second test it
can convert it into simple arithmetic. These are representative of
common optimization failures we see in Rust.
Fixes https://github.com/llvm/llvm-project/issues/69841.

[InstCombine] Regenerate all test checks (NFC)
Due to an improvement to name preservation, a lot of InstCombine tests now show spurious diffs when regenerated.
Rather than regenerating individual files when they get touched, mass-regenerate all UTC-based InstCombine tests. I have then reset a number of files showing suspicious diffs where the UTC output has clearly been manually adjusted. I apologize if I missed anything in the mass of changes.

[AsmParser] Remove typed pointer auto-detection
IR is now always parsed in opaque pointer mode, unless -opaque-pointers=0 is explicitly given. There is no automatic detection of typed pointers anymore.
The -opaque-pointers=0 option is added to any remaining IR tests that haven't been migrated yet.
