Valgrind, ppc: Fix test for 32-bit testsuite.
The 32-bit testsuite executes the 64-bit class instruction prtyd. This
instruction should not be tested in 32-bit mode. The change also updates
the expected output for the test. Note, 32-bit HW will generate a SIGILL
when the prtyd instruction is executed. However, the 64-bit HW executing
a 32-bit application does execute the instruction but only the lower 32-bits

fix 123837 semctl system call: 4rth argument is optional, depending on cmd
Depending on the semctl command (arg3), arg4 might or might not be needed.
The PRE(sys_ipc) multiplexed syscall for semctl was always checking
all 4 args.
The fix consists in dereferencing the 4th arg (which in sys_ipc is ARG5)
only if the semctl syscall cmd implies 4 arguments.
This avoids the false positive on linux x86.
Note that PRE(sys_ipc) is still too simplistic as it assumes
that 6 args are always read, which is not the case.
This seems to cause false positive on mips:
memcheck on none/tests/sem gives:
Syscall param ipc(fifth) contains uninitialised byte(s)
It would be nice to implement the multiplexed PRE(sys_ipc) by
calling the PRE(sys_xxxx) similar PRE, depending on ARG1 of sys_ipc.
This would then avoid the simplistic PRE(sys_ipc) logic without duplicating
the logic in PRE(sys_semctl) (and all other sys_ipc multiplexed syscalls).
However, I found no easy way to do that.
With the current fix, some logic about semctl is partially duplicated between
the PRE(sys_ipc) (for platforms such as x86 having a multiplexed sys call)
and PRE(sys_semctl) (for platforms such as amd64, having a direct sys call)
to fix the false positive encountered on x86.

This patch is the first installment of the cache info reorganisation.
It's reorg only. No new cache autodetection stuff has been added.
coregrind
pub_tool_cpuid.h is removed as it is no longer exposed to tools.
Its contents has moved to pub_core_cpuid.h.
New file: coregrind/m_cache.c to contain the autodetect code for
cache configurations and define other cache characteristics that
cannot be autodetected (i.e. icaches_maintain_coherence). Most of
cg-arch/x86-amd64.c was moved here. The cache detection code for
x86-64 needs to be fixed to properly initialise VexCacheInfo. It
currently has cachegrind bias.
m_cache.c exports a single function (to coregrind):
VG_(machine_get_cache_info)(VexArchInfo *vai)
This function is called from VG_(machine_get_hwcaps) after hwcaps have
been detected.
cachegrind
Remove cachegrind/cg-{ppc32,ppc43,arm,mips32,s390x,x86-amd64}.c
With the exception of x86/mamd64 those were only establishing a
default cache configuration and that is so small a code snippet that
a separate file is no longer warranted. So, the code was moved to
cg-arch.c. Code was added to extract the relevant info from
x86-amd64.
New function maybe_tweak_LLc which captures the code to massage the
LLc cache configuration into something the simulator can handle. This
was originally in cg-x86-amd64.c but should be used to all architectures.
Changed warning message about missing cache auto-detect feature
to be more useful. Adapted filter-stderr scripts accordingly.
