Created attachment 29595
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29595
gcc48-pr56548.patch

Untested fix.  Note I have no idea what performance issue on MIPS the patch
that regressed this was fixing and whether this fix doesn't undo that (or parts
thereof).  On the other side, unexpectedly returning a rtx in different mode
from what has been requested is a sure way to ICEs or miscompilations.
