* config/tc-mips.c (append_insn): Handle constant expressions with
no associated relocation.
(mips_ip): Cancel the expression after use for the Q format
specifier.
(parse_relocation): Return no relocation for unsupported
operators.
(my_getSmallExpression): Return no relocation if no relocation
operators are used.
