I originally made this script to show that scalarrepl didn't support them, but
it turned out it does. Better to still add the testcase then.

Fix <rdar://problem/6252129> implementation of method in category doesn't effectively declare it for methods below.

by decaying __builtin_va_list's type when forming builtins.  On
x86-64 (and other targets) __builtin_va_list is a typedef for
an array.

wasn't covering checking builtins like __builtin___vsnprintf_chk) with

it is needed. This eliminates a few hundred or so copies
of this code in each target.
