spirv: don't emit invalid debuginfo for buffer references
Currently no debug info is emitted for buffer reference types, which resulted in the SPIR-V backend code asserting when trying to emit the debug info for struct member that had such a type. Instead, the code now skips such struct members. Full debug info for buffer references may require forward references in the debug info instructions, which is currently prohibited by the spec.
