[FunctionAttrs][IR] Fix memory attr inference for volatile mem intrinsics (#122926)
Per LangRef volatile operations can read and write inaccessible memory:
> any volatile operation can read and/or modify state which is not
> accessible via a regular load or store in this module
Model this by adding inaccessible memory effects in getMemoryEffects()
if the operation is volatile.
In the future, we should model volatile using operand bundles instead.
Fixes https://github.com/llvm/llvm-project/issues/120932.
