Necessary changes to Valgrind to support MIPS64LE on Linux.
Minor cleanup/style changes embedded in the patch as well.
The change corresponds to r2687 in VEX.

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.

VG_(machine_get_hwcaps) for all architectures in pub_core_machine.h
and avoid double maintenance.

AUXV at startup, rather than by trying to execute a Neon instruction
and seeing whether it SIGILLs. Apparently the latter is not a
reliable way to ascertain the presence of usable Neon support. Fixes
#249775.

* track guest_R15 -> guest_R15T renaming
* change min instruction size to 2
* tidy up VG_(get_IP) etc functions a bit
* add hwcaps detection code for ARM

the changes to do with reading and using ELF and DWARF3 info.
This breaks all targets except amd64-linux and x86-linux.

I tried using 'svn merge' to do the merge but it did a terrible job and
there were bazillions of conflicts. So instead I just took the diff between
the branch and trunk at r10155, applied the diff to the trunk, 'svn add'ed
the added files (no files needed to be 'svn remove'd) and committed.

DARWIN branch. A big ugly DARWIN/trunk sync commit, mostly to do with
changing the representation of SysRes and vki_sigset_t. Functionality of
the trunk shouldn't be changed by it.

bit of an ugly hack (see comments in m_machine.c) which is suitable
for merging into 3_0_BRANCH, but should be cleaned up once that's
done.

bit-rotted badly and was clogging up the code.
I put the useful remnants in docs/porting-to-ARM in case anyone ever
wants to try porting to ARM again.

array at startup. This is used in m_transtab. However this info is
not yet fed to Vex, so it's still important to zero-out the auxv field
holding cache line size info passed to the client, so as to stop the
client's glibc using dcbz. This will be fixed.
Also get rid of a bunch more ppc32-specific vdso stuff in m_main that
doesn't need to be done. This now means ppc32-linux specifics in
m_main are only marginally intrusive than the x86-linux or amd64-linux
specifics in m_main.

things. These made sense when the arch/OS/platform-specific code was in
one module, but as that code got mixed in with generic code the boundary
between generic and non-generic blurred, and the distinction made less
sense. So let's get rid of them.

Plenty still to do, but simple programs like ls seem to run ok
Thanks, Paul, for having your ppc port of valgrind 2.4 to work from!
