pending interrupts.
* interrupts.c (interrupts_process): Keep track of the last number
of masked insn cycles.
(interrupts_initialize): Clear last number of masked insn cycles.
(interrupts_info): Report them.
(interrupts_update_pending): Compute clear and set masks of
interrupts and clear the interrupt bits before setting them
(due to SCI interrupt sharing).

* armdefs.h (struct ARMul_State): New members `LastTime' and
`CP14R0_CCD' used for the timer/counters.

(ARMul_Emulate32, ARMul_Emulate26): Clean up function definition.
(ARMul_Emulate32): Handle the clock counter and hardware instruction
breakpoints. Call XScale_set_fsr_far() for software breakpoints and
software interrupts.
(LoadMult): Call XScale_set_fsr_far() for data aborts.
(LoadSMult): Likewise.
(StoreMult): Likewise.
(StoreSMult): Likewise.
* armemu.h (write_cp15_reg): Update prototype.
* arminit.c (ARMul_NewState): Initialise CP14R0_CCD and LastTime.
(ARMul_Abort): If XScale, check for FIQ and IRQ being enabled in CP13
register 0.
* armvirt.c (GetWord): Call XScale_check_memacc().
(PutWord): Likewise.
PENDING_FILL. Use PENDING_SCHED directly to handle the pending
set of the FCSR.
* sim-main.h (COCIDX): Remove definition; this isn't supported by
PENDING_FILL, and you can get the intended effect gracefully by
calling PENDING_SCHED directly.
