…g mismatches Original change: KhronosGroup@bdd7652 Non-constant @llvm.memset calls are presently lowered by generating synthetic functions with the mangled name of memset. However, the reader tries to use this name to generate the intrinsic call again. This causes verification issues if the SPIRVWriter and SPIRVReader do not agree on whether or not to use opaque pointers. This change uses the actual type of the function (which will take into account whether or not it is in opaque pointer mode) to generate the LLVM intrinsic name, fixing the mismatch issues.
