This disconnects a good chunk of the alias set circuitry in ASIS mode because
it was bypassing kludges put in place for this mode specifically.

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

	* gcc-interface/decl.c (gnat_to_gnu_entity): Do not bother about alias
	sets of derived types in ASIS mode.
