    When a numeric literal with leading zeroes was seen in the parser, it
    would only be accepted if it were a valid hex or octal literal.  Any
    invalid numeric literal would be split up into multiple tokens: the
    valid hex/octal literal followed by the rest of the characters.
    Instead, when scanning a numeric literal with leading zeroes, always
    accept the number and give an appropriate error if the accepted number
    does not fit in the expected base.

"*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 "*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.
