This adapts the compiler to the changes required by llvm/llvm-project@304f1d5.
AFAICT,
WriteOnlyisn't used by the compiler, allReadNoneuses were migrated and the remaining use ofReadOnlyis only for function parameters.To simplify the FFI, this PR uses an enum to represent
MemoryEffectsacross the FFI boundary, which then gets mapped to the matching static factory method when constructing the attribute.Fixes #103961.
