Log Message:
gcc: Fix peephole optimization bug for sh3 (PR port-sh3/56311)

Cherry-picked from upstream:
https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=4dbb3af1efe55174a714d15c2994cf2842ef8c28
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101469

Now, the PR confirmed fixed. No regression observed for full ATF run on
landisk (compared with GCC built with this peephole optimization being
removed by hand).

We thank Oleg Endo, the author of the upstream commit.

Also thanks hgutch@ and uwe@ for analysis.
