05fe123a9e Update copyright notice for 2005 on all relevant files. Don't bother trying
to be selective about it.

f224865e9e Fix enough stuff so it will start up and run for a few bbs on amd64,
before dying.

efcf1e61ec Complete rewrite (I think this is the 4th incarnation) of translation
table/cache management.  Two main changes.  (1) Translation areas are
recorded using VexGuestExtents, so that Vex is now properly supported
and code deletion works correctly.  (2) Low overhead BB profiling,
enabled by the --profile-flags=<XXXXXXXX> option.  This finds the top
N bbs at exit and shows them, so as to give a basis from which to do
performane tuning.

To support this, the way tt/tc work is changed.  It is still a
sectored arrangement, but now each sector has its own hash table.
This simplifies a lot of things.

2d5d04c3d1 Ensure host CPU is in the state that VEX-generated code expects prior
to running any such code.

4c5b50284b Set host FPU mode to the default mode expected by VEX generated code.
ToDo: set SSE control word correctly too, and also D flag.

ce2585d447 Changed message at the top of files, and the startup message, and the
string in valgrind.pc.in, so that they describe Valgrind as a "dynamic
binary instrumentation framework", and don't mention platforms at all.  

I had to tweak the regtest filters a bit for this.

b4421b93e7 Implemented the dispatch loop for AMD64. Works at least enough to do
through once, failing to find the translation, and falling back to the
scheduler.

Did a couple of minor associated cleanups too.

c4b75e59c9 Move VG_(have_ssestate) out of core and into coregrind/x86/.
Also fixed up out-of-date comments for run_innerloop.

146a07a91f Remove string "panic_msg_ebp" from x86/dispatch.S and amd64/dispatch.S,

86ef8a5a44 Get rid of all vestiges of translation-chaining, and generally clean
up and paranoidise the translation cache management.

5cc18c19a2 Moved the variable VGOFF_(m_eip) from x86, and moved it (and its
computation) into the generic core, because it's needed by the dispatch
loop of all archs.  Also renamed it VG_(instr_ptr_offset), which is
clearer.  Since it was the last use of the VGOFF_ prefix, I removed that
prefix.  

Also cleaned up the ARM stubs slightly, by removing some of the copied,
commented-out x86 code which has since fallen out of date with the real
x86 code and was thus misleading.

3558db91b1 Get rid of baseBlock. Now, when generated code is running, the guest
state pointer points directly at the ThreadState.arch.vex field, thus
updating it in place and avoiding a lot of code (and time-wasting)
which copies stuff back and forth to baseBlock.

Fix zillions of other places in the system where the current thread id
is needed.  It is now passed to all needed places.
