Max Filippov 4b37aaa879 target/xtensa: fix ICACHE/DCACHE options detection 
Configuration overlay does not explicitly say whether there are ICACHE
and DCACHE in the core. Current code uses XCHAL_[ID]CACHE_WAYS to detect
if corresponding cache option is enabled, but that's not correct: on
cores without cache these macros are defined as 1, not as 0.
Check XCHAL_[ID]CACHE_SIZE instead.

Max Filippov d2132510ca target/xtensa: support icount 
Delimit each instruction that may access timers or IRQ state with
qemu_io_start/qemu_io_end, so that qemu-system-xtensa could be run with
-icount option.

Raise EXCP_YIELD after CCOMPARE reprogramming to let tcg_cpu_exec
recalculate how long this CPU is allowed to run.

RSR now may need to terminate TB, but it can't be done in RSR handler
because the same handler is used for XSR together with WSR handler, which
may also need to terminate TB. Change RSR and WSR handlers return type
to bool indicating whether TB termination is needed (RSR) or has been
done (WSR), and add TB termination after RSR/WSR dispatcher call.

Max Filippov 59a71f7578 target/xtensa: refactor CCOUNT/CCOMPARE 
Xtensa cores may have a register (CCOUNT) that counts core clock cycles.
It may also have a number of registers (CCOMPAREx); when CCOUNT value
passes the value of CCOMPAREx, timer interrupt x is raised.

Currently xtensa target counts a number of completed instructions and
assumes that for CCOUNT one instruction takes one cycle to complete.
It calls helper function to update CCOUNT register at every TB end and
raise timer interrupts. This scheme works very predictably and doesn't
have noticeable performance impact, but it is hard to use with multiple
synchronized processors, especially with coming MTTCG.

Derive CCOUNT from the virtual simulation time, QEMU_CLOCK_VIRTUAL.
Use native QEMU timers for CCOMPARE timers, one timer for each register.
