Except if we don't recompute, my testcase will fail because we haven't
seen any TM builtins in tree-ssa-structalias.c:find_func_aliases().

I guess if what y'all want is alias info for builtins created by hand
then I'll just rewrite my testcase with manually created builtin calls.

Is this what you want?
