SMP support for ARMv6/v7 HW watchpoints

Use per-CPU structure to store HW watchpoints registers state
for each CPU present in the system. Those registers will be restored
upon wake up from the STOP state if requested by the debug_monitor
code. The method is similar to the one introduced to AMD64.

We store all possible 16 registers for HW watchpoints
(maximum allowed by the architecture).
HW breakpoints are not maintained since they are used for single
stepping only.

Add two new pmap functions:
vm_offset_t pmap_quick_enter_page(vm_page_t m)
void pmap_quick_remove_page(vm_offset_t kva)

These will create and destroy a temporary, CPU-local KVA mapping of a specified page.

Guarantees:
--Will not sleep and will not fail.
--Safe to call under a non-sleepable lock or from an ithread

Restrictions:
--Not guaranteed to be safe to call from an interrupt filter or under a spin mutex on all platforms
--Current implementation does not guarantee more than one page of mapping space across all platforms. MI code should not make nested calls to pmap_quick_enter_page.
--MI code should not perform locking while holding onto a mapping created by pmap_quick_enter_page

The idea is to use this in busdma, for bounce buffer copies as well as virtually-indexed cache maintenance on mips and arm.

NOTE: the non-i386, non-amd64 implementations of these functions still need review and testing.

Rework the VFP code that handles demand-based save and restore of state.

The old code was full of complexity that would only matter if the
kernel itself used the VFP hardware. Now that's reduced to either killing
the userland process or panicking the kernel on an illegal VFP instruction.

This removes most of the complexity from the assembler code, reducing it
to just calling the save code if the outgoing thread used the VFP.

The routine that stores the VFP state now takes a flag that indicates
whether the hardware should be disabled after saving state. Right now it
always is, but this makes the code ready to be used by get/set_mcontext()
(doing so will be addressed in a future commit).

Remove the arm-specific pc_vfpcthread from struct pcpu and use the MI
field pc_fpcurthread instead.
