[PATCH/RFC] Trim "tm-i386v.h"

[Mark Kettenis <kettenis@wins.uva.nl>]

AFIACT we can remove a lot of junk "tm-i386v.h".  The generic i386
versions in "tm-i386.h" should work fine since the System V ABI is the
de facto standard ABI.  The only thing that remains is
START_INFERIOR_TRAPS which indeed is a System V-specific thing.

If nobody speaks up in the coming week, I intend to commit the
attached patch.

from  Mark Kettenis  <kettenis@gnu.org>

	* config/i386/tm-i386v.h: Don't include "regcache.h".
	(EXTRACT_RETURN_VALUE, STORE_RETURN_VALUE, FRAME_CHAIN,
	FRAMELESS_FUNCTION_INVOCATION, FRAME_SAVED_PC, FRAME_NUM_ARGS):
	Remove macros.  The versions from "tm-i386.h" should work fine
	(and in most cases even better).
