If strchr can't be folded in gimple-fold...

Browse source 
If strchr can't be folded in gimple-fold, we still need to fall into
the generic code so the folding code in builtins.c is also called.

    gcc/
	* gimple-fold.c (gimple_fold_builtin): After failing to fold
	strchr, also try the generic folding.
