a9b2103cf2 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.
