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.

This saves instructions in hot path, resulting in
3% improvement on average with perf benchmarks.

Makes modifications simpler in the future, and
should result in the same code.
This patch was already discussed some time ago on the
dev mailing list, and did not make a difference on
various architectures.

Some hardware platforms will return "unknown" for 'uname -i', so it is more
accurate and common to run 'uname -m' which returns machine hardware name.
This way, some platforms that do not support sgcheck will avoid running tests
for it.

coregrind/m_translate.c does not compile on ppc64 (ppc32 maybe also?)
due to missing include file.
Note: libvex_emnote.h is unconditionally included, even if only
useful for ppc. I suppose we do not want #ifdef for that.

Massif does not accept to take snapshots of heap before execution has started.
So, if such a snapshot is requested (using vgdb and option --vgdb-error=0),
then such a snapshot must be refused rather than causing an assert.

With some glibc version (e.g. on fedora 16), gdb output contains
a line with T_PSEUDO which should be filtered out.

Valgrind for MIPS will give more details on the heap allocation functions
(operator new) than the existing post.exp presents.
This fixes massif/tests/overloaded-new for MIPS and likely other arch if they
provide the info.

struct pthread_mutex_t is different on MIPS32 and x86_64, and thus passing a
bogus mutex pthread_cond_wait (line 72) will corrupt memory in a different way
on two platforms. This causes the subsequent call to pthread_cond_wait to fail
on MIPS and i386 but not on x86_64.
This change fixes helgrind/tests/tc23_bogus_condwait on MIPS and i386.

Writing to a double is done via two store-word instructions on MIPS platforms.
Thus, Helgrind will report "Possible data race during write of size 4" twice on
subsequent locations on MIPS instead of a single "Possible data race during
write of size 8". New exp file is added to cover this case.
This fixes helgrind/tests/tc19_shadowmem on MIPS.

Different error numbers on MIPS require us to add an extra exp file for this
test. EDEADLK is 45 on MIPS (and not 35), and EOPNOTSUPP is 122 (and not 95).
Furthermore, sem_post will pass due to different implementation on MIPS (in
comparison to x86_64), and thus one error less has to be reported in the log.
This fixes helgrind/tests/tc20_verifywrap.
