* cp1.c (store_fpr): Remove #ifdef'd out call to UndefinedResult
which wouldn't compile anyway.
* sim-main.h (unpredictable_action): New function prototype.
(Unpredictable): Define to call igen function unpredictable().
(NotWordValue): New macro to call igen function not_word_value().
(UndefinedResult): Remove.
* interp.c (undefined_result): Remove.
(unpredictable_action): New function.
* mips.igen (not_word_value, unpredictable): New functions.
(ADD, ADDI, do_addiu, do_addu, BGEZAL, BGEZALL, BLTZAL, BLTZALL)
(CLO, CLZ, MADD, MADDU, MSUB, MSUBU, MUL, do_mult, do_multu)
(do_sra, do_srav, do_srl, do_srlv, SUB, do_subu): Invoke
NotWordValue() to check for unpredictable inputs, then
Unpredictable() to handle them.
