[InstCombine] Optimize away certain additions using modular arithmetic

This is only worth doing if the sequence is the sole user of the addition
operation.

[InstCombine] Extend `(icmp eq/ne (and Z, X), (and Z, Y))` folds
Two ways to relaxed:
1) Only require one of the `and` ops to be single-use if both `X`
and `Y` are constant.
2) Special case, if `X ^ Y` is a negative power of 2, then
`Z ^ NegP2 ==/!= 0` will fold to `Z u</u>= -NegP2` which
creates no additional instructions so fold irrelivant of
use counts.
Closes #94867

[InstCombine] use decomposeBitTestICmp to make icmp (trunc X), C more consistent
This is a follow-on suggested in D112634.
Two folds that were added with that patch are subsumed in the call to
decomposeBitTestICmp, and two other folds are potentially inverted.
The deleted folds were very specialized by instcombine standards
because they were restricted to legal integer types based on the data
layout. This generalizes the canonical form independent of target/types.
This change has a reasonable chance of exposing regressions either in
IR or codegen, but I don't have any evidence for either of those yet.
A spot check of asm across several in-tree targets shows variations
that I expect are mostly neutral.
We have one improvement in an existing IR test that I noted with a
comment. Using mask ops might also make more code match with D114272.
