[patch committed] Fix PR target/27182

[Kaz Kojima]

I've applied the attached patch to the trunk and the 4.1 branch
under the Joern's approval in

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27182

to fix PR target/27182 which is a wrong-code problem on SH.
The PR is a 4.1/4.2 regression because the define_peephole2 causing
the problem was introduced after 4.0, though the PR is reported for
4.1.
The patch is tested with bootstrap and the top level "make -k check"
for the mainline and the 4.1 branch on sh4-unknown-linux-gnu with
no new failures.

Regards,
	kaz
