Hi!

In my recent patch
http://gcc.gnu.org/ml/gcc-patches/2011-06/msg01609.html
I've missed a spot where it was special casing the builtins that
don't return their first argument, but instead of that return their
first argument plus something.

Fixed thusly, committed as obvious.

	* tree-ssa-structalias.c (find_func_aliases_for_builtin_call): Fix
	handling of BUILT_IN_MEMPCPY_CHK and BUILT_IN_STPCPY_CHK.
