Florian Hahn b10c62b2d9 [VPlan] Don't merge allocas across lanes, parts or recipes. (#229929) ...

Each execution of an alloca creates a new allocation, distinct from the
allocations of all other executions. They must not be merged, either by
CSE or via isUniformAcrossVFsAndUFs.

Update those to explicitly handle Alloca recipes.

Fixes https://github.com/llvm/llvm-project/issues/229389.
