Richard,

This patch fixes a trivial problem in gimplify_parameters, introduced by the
patch that introduced BUILT_IN_ALLOCA_WITH_ALIGN.
BUILT_IN_ALLOCA_WITH_ALIGN has 2 parameters, so the number of arguments in the
corresponding build_call_expr should be 2, not 1.

Bootstrapped and reg-tested (including Ada) on x86_64.

OK for trunk?

Thanks,
- Tom

	* function.c (gimplify_parameters): Set number of arguments of call to
	BUILT_IN_ALLOCA_WITH_ALIGN to 2.
