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.

rs6000: Fix PR67344

The "*and<mode>3_imm_dot_shifted" pattern is a define_insn_and_split,
like most "dot" patterns: if its output is not assigned cr0 but some
other cr reg, it splits to a non-dot insn and a compare.

Unfortunately that non-dot insn will clobber cr0 as well.  We could
add another clobber (with "=X,x"), but then that second alternative
is never useful; instead, just remove that second alternative.
