Major i386 testsuite regressions on trunk

[Rainer Orth]

I've been able to pinpoint the single patch that causes the i386 testsuite
regressions reported in

	http://gcc.gnu.org/ml/gcc-bugs/2002-05/msg01111.html

Bootstrapping the trunk as of 20020511 17:00, results are fine.  Updating
to 20020511 17:30, i.e. with this patch added

Sat May 11 14:34:35 CEST 2002  Jan Hubicka  <jh@suse.cz>

	* i386.md (testsi to testqi spliters): New.

	2002-01-14  Josef Zlomek  <zlomek@matfyz.cz>

	cfg.c (dump_edge_info): added dumping of EDGE_CAN_FALLTHRU.

	Wed Jan  9 2002  Josef Zlomek  <zlomj9am@artax.karlin.mff.cuni.cz>

	* basic-block.h: New flag EDGE_CAN_FALLTHRU
	* cfganal.c (set_edge_can_fallthru_flag): New function; marks the edges
	that can be made fallthru.

	Mon Nov 12 16:25:53 CET 2001  Jan Hubicka  <jh@suse.cz>

	* cfglayout.c (cleanup_unconditional_jumps): New static function.
	(cfg_layout_initialize): Use it.

I get many testsuite regressions in a (C only) bootstrap on
i386-pc-solaris2.8:

As can be seen in the testsuite results pointed out in my original report
above, many more are caused for other languages.
