powerpc: Handle DImode rotatert implemented with rlwinm (PR69946)

Some DImode rotate-right-and-mask can be implemented best with a rlwinm
instruction: those that could be a lshiftrt instead of a rotatert, while
the mask is not right-aligned.  Why the rotate in the testcase is not
optimised to a plain shift is another question, but we need to handle
it here anyway.  We compute the shift amount for a 64-bit rotate.  This
is 32 too high in this case; if we print using %h that is masked out (and
this doesn't silently let through invalid instructions, everything is
