This seems to have caused a bootstrap failure on hppa.  A QImode value
is passed in a SImode reg and then should get extended to DImode; we
must make sure we use a qidi extension.  The following patch does that;
I've not heard back whether it fixes the hppa bootstrap, but it seems to
work on arm-linux (one extra testsuite failure caused by an unrelated
change in the same tree).  Also bootstrapped on i686-linux.  Ok?
