With virtual IRQ support added, software now can fully use the whole local interrupt range without any actual hardware attached.

For RISC-V, GDB treats single-step similarly to breakpoint: add a breakpoint at the next step address, then continue. So this also works for single-step debugging. Implement kvm_arch_update_guest_debug(): Set the control flag when there are active breakpoints. This will help KVM to know the status in the userspace. Add some stubs which are necessary for building, and will be implemented later.

Add the CSR number though the implementation is just reading zero and writing ignore. Besides, for accessing HEDELEGH, it should be controlled by mstateen0 'P1P13' bit.

Without this being set, proper backend is not created when option like -cdrom is used. So, make the virt board's default block device type be IF_VIRTIO similar to other architectures. We also need to set no_cdrom to avoid getting a default cdrom device.

Add an instructions bool parameter to get_ticks() to correctly return icount_get_raw() when icount_enabled() == 1 and instruction count is queried.

The implied extensions are enabled recursively, so we don't have to expand all of them manually. This also eliminates the old-fashioned ordering requirement.

This commit adds trigger_common_match() to prepare the common matching conditions for the type 2/3/6 triggers. For now, we just implement trigger_priv_match() to check if the enabled privilege levels of the trigger match CPU's current privilege level. Remove the related code in riscv_cpu_debug_check_breakpoint() and invoke trigger_common_match() to check the privilege levels of the type 2 and type 6 triggers for the breakpoints. This commit also changes the behavior of looping the triggers. In previous implementation, if we have a type 2 trigger and env->virt_enabled is true, we directly return false to stop the loop. Now we keep looping all the triggers until we find a matched trigger. Only the execution bit and the executed PC should be futher checked in riscv_cpu_debug_check_breakpoint().
