Subject: [PATCH] [clang][wasm] Resolve assertion errors caused by converting
ComplexType to RecordType
When a function parameter is of the built-in Complex type in Clang,
the conversion from ComplexType to RecordType is not possible, resulting in a
crash in Clang.
RecordType is a helper class for structs, unions, and classes.
