[VPlan] Transform reverse loads into vp.strided.load with -1 stride

Rebased from the WIP on loop-vectorize/reverse-vp-strided-load.

After simplifyReverses pulls reverses out of elementwise recipes, look
through single-use elementwise trees under a reverse to the reverse
consecutive loads at their leaves (live-ins are allowed as splats), and
replace each load with a vp.strided.load with a negative stride when it
is legal and cheaper than the loads plus the reverse. This is the VPlan
equivalent of RISC-V's performReverseEVLCombine.

Fixes #204154.

[RISCV][P-ext] Disable useRVVForFixedLengthVectors when P is enabled. (#240636)

We haven't done anything to select priority for P or RVV. Right now the
setOperation action calls run for both and leave things in a weird
state.

This patch disables useRVVForFixedLengthVectors when P is enabled so we
only run one set of setOperationAction calls for fixed vectors. This is
the lowest effort fix and I suspect there are still more issues.

Fixes #240534.

[InferAddressSpaces] Use a new value map for each rewritten constant (#240662)

When the pass rewrites a flat constant expression, it remaps the
instructions that use it through other constant expressions with a
`ValueMapper`. All rewritten constants shared one map, and the mapper
caches every constant that it visits, including the ones that it maps to
themselves. So when one instruction uses two rewritten constants, the
remap for the first one caches the part with the second one as
unchanged, and the remap for the second one reuses that entry. For
example, if a call has `addrspacecast`s of two flat pointers that are
based on the same `addrspace(3)` global, only one argument is folded.
This PR uses a new map for each rewritten constant.

This PR was assisted by AI but I reviewed all the changes.
