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
cpu_class_set_{do_unassigned_access,vmsd}() and device_class_set_vmsd()....

cpu: Turn cpu_dump_{state,statistics}() into CPUState hooks

Make cpustats monitor command available unconditionally.

Prepares for changing kvm_handle_internal_error() and kvm_cpu_exec()
arguments to CPUState.

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...

Rename target_phys_addr_t to hwaddr

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,...

target-alpha: Make use of fp_status.flush_inputs_to_zero.

This softfp feature post-dates the last major update to the Alpha
fpu translation. We can make use of this to eliminate at least
one helper function that was performing this operation by hand.

There's no need to attempt to match EXCP_* values with PALcode entry
point offsets. Instead, compress all the values to make for more
efficient switch statements within QEMU.
