[PATCH v3 00/13] exec: Rework around CPUState user fields (part 2)

[Philippe Mathieu-Daudé]

Missing WASM testing by Ilya (branch available at
https://gitlab.com/philmd/qemu/-/commits/tcg_flush_jmp_cache)

Since v2:
- Move cpu_loop_exit_requested() to "exec/cpu-loop.h"
- Added R-b tags

Since v1:
- First 13 patches queued
- Restrict qemu_plugin_vcpu_exit_hook() to (TCG) plugins
- Restrict cpu_plugin_mem_cbs_enabled() to TCG (plugins)
- Addressed Richard review comments on the others:
  - Move cpu_plugin_mem_cbs_enabled()
  - Do not move mem_io_pc, waiting for [*]
  - Mention can_do_io restricted

Finish extracting TCG fields from CPUState:
- Extract tcg_cpu_exit() from cpu_exit()
- Introduce AccelOpsClass::exit_vcpu_thread()
- cpu_exit() calls exit_vcpu_thread=tcg_cpu_exit for TCG
- Forward declare TaskState and more uses of get_task_state()
- Introduce TCG AccelCPUState
- Move TCG specific fields from CPUState to AccelCPUState
- Restrict "exec/tlb-common.h" to TCG
- Restrict iommu_notifiers, icount to system emulation
