51fcc51321 MIPS: Add the lo register to the clobber list in the madd-8.c and msub-8.c testcases. 
The lo register is not listed in the clobber list in the inline asm statement
for the madd-8.c and msub-8.c testcases.  This means that when building for the
n64 ABI GCC is free to use the lo register instead of the stack when 
saving/restoring the clobbered registers.  Then then means that it decides to 
use the msub/madd instruction to perform the "x - y * z" operation rather than 
using mul; addu/subu which the test is looking for.

353e462df7 [RS6000] Correct constraints for ior<mode>_mask 
ior<mode>_mask always splits to rtl matching rotl<mode>3_insert.  The
latter requires one of its input operands match the output, so let
reload/lra know the equivalent operand match must also occur for
ior<mode>_mask.

	PR target/67356
	* config/rs6000/rs6000.md (ior<mode>_mask): Use constraint "0"
	for operand 1.
