Currently clang doesn't verify if the first argument in _builtin_assume_aligned_ is of pointer type. This leads to an assertion build failure. This patch aims to add a check if the first argument is of pointer type or not and diagnose it with `diag::err_typecheck_convert_incompatible` if its not of pointer type.
