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

compiler: Don't record dependencies of invalid redefinitions.

    The gofrontend would crash when trying to find the initialization
    order of a variable list where one of the listed variables was an
    invalid redefinition of another in a call statement.  This patch

rs6000: Fix PR67346

"*ior<mode>_mask" is a define_insn_and_split, so it shouldn't use
can_create_pseudo in its instruction condition, because IRA can then
create such an instruction, and the condition becomes false before
the insn is split.  Use a scratch instead.

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.
