This adds support for __builtin_prefetch in Ada.

Tested on x86_64-suse-linux, applied on the mainline.


2019-05-28  Eric Botcazou  <ebotcazou@adacore.com>

	* gcc-interface/decl.c (intrin_arglists_compatible_p): Do not return
	false if the internal builtin uses a variable list.

	* gnat.dg/prefetch1.ad[sb]: New test.
