[ConstantFold] Remove notional over-indexing fold (#93697)
The data-layout independent constant folding currently has some rather
gnarly code for canonicalizing GEP indices to reduce "notional
overindexing", and then infers inbounds based on that canonicalization.
Now that we canonicalize to i8 GEPs, this canonicalization is
essentially useless, as we'll discard it as soon as the GEP hits the
data-layout aware constant folder anyway. As such, I'd like to remove
this code entirely.
This shouldn't have any impact on optimization capabilities.

[InferAlignment] Implement InferAlignmentPass
This pass aims to infer alignment for instructions as a separate pass,
to reduce redundant work done by InstCombine running multiple times. It
runs late in the pipeline, just before the back-end passes where this
information is most useful.

[InferAlignment] Create tests for InferAlignment pass
These tests are in preparation for the InferAlignment pass. They consist
mainly of tests that break when alignment inference is disabled in
LoadInst and StoreInst within InstCombine.
