Due to limitations in GISel / IRTranslator, the SPIR-V BE replaces aggregate function args with `i32` placeholders, which are subsequently used to retrieve the original type after IR translation, from metadata. Due to what appears to be an oversight, the current implementation only handles a single mutation, as it does not traverse the metadata, but rather only takes the first operand. This patch addresses that limitation by correctly iterating the metadata.
