since it appears that some part of the vast stack of libraries that
supports LibreOffice actually abuses it thusly.

Iop_Mul8, Iop_Sar8, Iop_CmpwNEZ32, and Iop_8HLto16.
With this change mc_translate now handles all IR ops which are architecture
independent, except Iop_LeftXYZ and Iop_Max32U.

After looking more in depth, gdbserver must not be terminated
in PRE(posix_spawn) on MacOS: this is running in the parent and
(on MacOS) is a single syscall similar to a fork+exec.
On linux, posix_spawn is implemented using 2 syscalls
(fork followed by exec).

(patch from Petar Jovanovic).
The mips specific code of vgdb.c was storing the arguments
at wrong places in the ptrace setreg. This caused the blocked syscall(s)
to return with an error rather than to be properly restarted.
With this commit, the gdbsrv tests are not blocking anymore
with Valgrind mips32 running on mips64 GNU/Linux.
vgdb is believed to be functional, even if process is blocked in a syscall.
The following tests are still failing
gdbserver_tests/mcbreak (stdout)
gdbserver_tests/mcbreak (stdoutB)
gdbserver_tests/mcbreak (stderrB)
gdbserver_tests/mcsignopass (stderr)
gdbserver_tests/mcsignopass (stdoutB)
gdbserver_tests/mcsigpass (stderr)
gdbserver_tests/mcsigpass (stdoutB)
gdbserver_tests/nlcontrolc (stdoutB)
gdbserver_tests/nlsigvgdb (stderr)
gdbserver_tests/nlsigvgdb (stderrB)
Of the above, nlsigvgdb failure is still strange.
Others looks like "normal" differences due e.g. to mips specific gdb
behaviour and/or none/tests/faultstatus (re-used in gdbsrv tests)
behaving differently on mips.

This should fix the bug (but could not test it : no MacOSX).
See equivalent code in syswrap-generic.c and comment
in pub_tool_gdbserver.h:
// tid == 0 indicates to stop gdbserver and report to gdb
// that the valgrind-ified process has exited.

On mips32, 10 is SIGBUS. This was making all tests using
simulate_control_c looping for ever or a long time.

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.

Otherwise the function redirections / client requests seem
to get confused. Symptoms are error messages such as
