For the PER storage-alteration event we can use the QEMU watchpoint

from the default ASC.

The tb_check_watchpoint function currently assumes that all memory
access is done either directly through the TCG code or through an
helper which knows its return address. This is obviously wrong as the
helpers use cpu_ldxx/stxx_data functions to access the memory.
Instead of aborting in that case, don't try to retranslate the code, but
assume that the CPU state (and especially the program counter) has been
saved before calling the helper. Then invalidate the TB based on this
address.

For the PER instruction-fetch, we can't use the QEMU breakpoint
infrastructure as it triggers for a single address and not a full
address range, and as it actually stop before the instruction and
not before.
We therefore call an helper with the just fetched instruction address,
which check if the address is within the PER address range. If it is
the case, an event is recorded and will be signaled through an
exception.
Note that we implement here the PER-3 behaviour, that is an invalid
opcode is not considered as an instruction fetch. Without PER-3 this
behavious is undefined.

For the PER successful-branching event support, we can't rely on any
QEMU infrastucture. We therefore call an helper in all places where
a branch can be taken. We have to pay attention to the branch to next
case, as it's still a taken branch.
We don't need to care about the cases using goto_tb, as we have disabled
them in the previous patch.

This patch add basic support to generate PER exceptions. It adds two
fields to the cpu structure to record for the PER address and PER
code & ATMID values. When an exception is triggered and a PER event is
pending, the two PER values are copied to the lowcore area.
At the end of an instruction, an helper is checking for a possible
pending PER event and triggers an exception in that case. For that to
work with branches, we need to disable TB chaining when PER is
activated. Fortunately it's already in the TB flags.
Finally in case of a SERVICE CALL exception, we need to trigger the PER
exception immediately after.

mvc_fast_memmove is bypassing the softmmu functions, getting the
physical source and destination addresses using the mmu_translate
function and accessing the corresponding physical memory. This
prevents watchpoints to work correctly.
Instead use the tlb_vaddr_to_host function to get the host addresses
corresponding to the guest source and destination addresses through the
softmmu code and fallback to the byte level code in case the
corresponding address are not in the QEMU TLB or being examined through
a watchpoint. As a bonus it works even for area crossing pages by
splitting the are into chunks contained in a single page, bringing some
performances improvements. We can therefore remove the 8-byte
loads/stores method, as it is now quite unlikely to be used.
At the same time change the name of the function to fast_memmove as it's
not specific to mvc and use the same argument order as the C memmove
function.
