Log:
Shorten right-shift again in C++.

Back in SVN r131862 richi removed this code to fix PR 34235, but didn't
remove the parallel code from the C front-end because the bug had previously
been fixed in r44080.  This patch copies the code from C again.

        * typeck.c (cp_build_binary_op): Restore short_shift code.
