fix for SH

This patch set fixes the problem for the SH.
The patch to sh_output_mi_thunk should no longer be necessary in mainline,
AFAICR
Kaz has fixed the generic code to get the line number information initialized.
If we want to use this approach, a tm.texi patch needs to be added, and machine

specific patches for the other ports are needed to get benefit of this patch.

Another approach would be to make the gen* programs create a minumum insn
length function, and use that instead.
