+ SIGTRAP and SIGQUIT for _WIN32.

+ * gencode.c (build_instruction) [MUL]: Cast operands to word64, to
+ force a 64 bit multiplication.
+ (build_instruction) [OR]: In mips16 mode, don't do anything if the
+ destination register is 0, since that is the default mips16 nop
+ instruction.

+ * gencode.c (MIPS16_DECODE): SWRASP is I8, not RI.
+ (build_endian_shift): Don't check proc64.
+ (build_instruction): Always set memval to uword64. Cast op2 to
+ uword64 when shifting it left in memory instructions. Always use
+ the same code for stores--don't special case proc64.
+
* gencode.c (build_mips16_operands): Fix base PC value for PC
relative operands.
(build_instruction): Call JALDELAYSLOT rather than DELAYSLOT for a
(INDELAYSLOT, INJALDELAYSLOT): Define.
(simulate): Clear simJALDELAYSLOT when simDELAYSLOT is cleared.

+ (sim_monitor): handle flush_cache by ignoring it
