this patch causes regular bootstrap to assert

Assert message is:
/mnt/svn/gcc-trunk/libgcc/../gcc/libgcc2.c: In function
‘__mulvdi3’:
/mnt/svn/gcc-trunk/libgcc/../gcc/libgcc2.c:400:1: internal compiler error: in
delete_output_reload, at reload1.c:8543
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

which is:
gcc_assert(spill_reg_store[last_reload_reg + k] == 0);
