Metadata (via ValueAsMetadata) can reference constant expressions that may no longer be supported. These references can both be in function-local metadata and module metadata, if the same expression is used in multiple functions. At least in theory, such references could also be in metadata proper, rather than just inside ValueAsMetadata references in calls. Instead of trying to expand these expressions (which we can't reliably do), pretend that the constant has been deleted, which means that ValueAsMetadata references will get replaced with undef metadata. Fixes https://github.com/llvm/llvm-project/issues/68281.
