  -----------
  [ASan][AMDGPU] Fix Assertion Failure. (#79795)

Assertion failure `(i >= FTy->getNumParams() || FTy->getParamType(i) ==
Args[i]->getType()) && "Calling a function with a bad signature!"'. The
'llvm.memcpy' intercepted by ASan instrumentation pass is implemented by
it's own __asan_memcpy implementation. The second argument of
llvm.memcpy accepts ptr to addrspace(4), __asan_memcpy also has to
follow ptr to addrspace(4) convention.
