cris: Abort when a v10 takes interrupts while in a delayslot

This is an internal error as the CRISv10 should mask interrupts
while executing delay slots. Bail out sooner rather than later.

cpu: Turn cpu_get_phys_page_debug() into a CPUClass hook

Change breakpoint_invalidate() argument to CPUState alongside.

Since all targets now assign a softmmu-only field, we can drop helpers

target-cris: Override do_interrupt for pre-v32 CPU cores

Instead of forwarding from cris_cpu_do_interrupt() to do_interruptv10(),
override CPUClass::do_interrupt with crisv10_cpu_do_interrupt() in the
newly introduced class_init functions.

cpu: Move halted and interrupt_request fields to CPUState

Both fields are used in VMState, thus need to be moved together.
Explicitly zero them on reset since they were located before
breakpoints.

cpu: Replace do_interrupt() by CPUClass::do_interrupt method

This removes a global per-target function and thus takes us one step
closer to compiling multiple targets into one executable.

It will also allow to override the interrupt handling for certain CPU...

Large page TLB flush

QEMU uses a fixed page size for the CPU TLB. If the guest uses large
pages then we effectively split these into multiple smaller pages, and
