Stack trace

The following code causes an assertion `DelayedTypos.empty()` in clang/sema
with message `Uncorrected typos!`:

void A() {
  __builtin_astype(x, x);
}

Full stack trace attached. Changing the second argument as such:

void A() {
  __builtin_astype(x, int);
}

Causes an unreachable in ASTContext.cpp with message `Unknown builtin type!`.

Using argument -fno-spell-checking prevents both errors.</pre>
