Fix for mips bootstrap failure

[Andreas Jaeger]

As reported on gcc-bugs (with subject "align bug? in mips.c" in
< http://gcc.gnu.org/ml/gcc-bugs/2000-04/msg00173.html >), we're passing
the wrong alignment to move_by_pieces.  The appended patch fixes this
bug.  

Please add this patch to gcc.

Thanks,
Andreas

	* config/mips/mips.c (expand_block_move): Pass alignment
	argument to move_by_pieces in bits, not bytes.
