This is infintely less painful than to find out how to invert
the condition in a test prerequisite.

Option sp-at-mem-access can be used by tools which do not
need an up to date BP and IP at each mem access.
It is needed however to have SP up to date at each memory
access, as an up to date SP is needed to grow the stack in
m_signals.c
Tools massif, cachegrind and callgrind are using sp-at-mem-access
as default.
None tool could also use sp-at-mem-access but default is kept
to unwindregs-at-mem-access (similar to memcheck, drd, helgrind, exp-sgcheck).
exp-dhat, exp-bbv, lackey have not been looked at to see if they
could make use of sp-at-mem-access.
Validated on x86, amd64, ppc64 and s390x.

does not work, as conversion will stop at the first invalid character.
So... need to loop over them.

* Option --vex-iropt-precise-memory-exns has been removed.
It is replaced by --vex-iropt-register-updates which accepts
3 values : 'unwindregs-at-mem-access' (replacing
--vex-iropt-precise-memory-exns=no), 'allregs-at-mem-access'
(replacing --vex-iropt-precise-memory-exns=yes)
and a new value 'allregs-at-each-insn'.
'allregs-at-each-insn' allows the Valgrind gdbserver to always
show up to date values to GDB.

* For tools replacing the malloc library (e.g. Memcheck, Helgrind, ...),
the option --redzone-size=<number> allows to control the padding
blocks (redzones) added before and after each client allocated block.
Smaller redzones decrease the memory needed by Valgrind. Bigger
redzones increase the chance to detect blocks overrun or underrun.

MIPS has different signal values, so it has to have its own expected output for
the tests that deal with signal values.
This fixes (false) failure in none/tests/async-sigs.

- advance the guest_IA to the next insn after raising the signal
- adjusting the address in a complaint to point to the failing insn
(after guest_IA has been advanced)
Update testcases .exp files.
