87f86e25b5 For now, disable test of: pmaddwd psadbw pslldq psrldq. The x86 front 
end doesn't yet handle them (nothing critically difficult), and they
are unlikely to turn up in compiler-generated code.

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.

ad1bf0073e Clear a few more AMD64 start-up hurdles: 
- implemented VG_(clone)()
- implemented PLATFORM_DO_MMAP()
- implemented VG_(init_thread1state)()  [will need to be updated as the
  Vex AMD64 guest state is updated]
- implemented OYNK, because it's useful

Also a couple of general cleaning up things.

782dd25de9 64-bit cleanness: fix nasty bug... in the memory allocators, redzones 
were being kept as UInts.  They were sometimes negated and then used as
indices to arrays, and on 64-bit platforms they get converted
incorrectly (using zero-extension instead of sign extension, I think)
before the indexing happens, giving a totally bogus index.

The fix was to convert all these types to SizeT.  It would be nice to be
able to avoid this automatically somehow in the future.

244787cc7f Get AMD64 slightly further before dying: 
- implemented VG_(do_syscall)()
- fixed a problem in ume.c with mapping when loading, which was causing
  stage2's memory to be trashed
- fixed stage2.lds substitution so stage2 goes in the right address

7a75a9f583 Overhauled the docs. Removed all the HTML files, put in XML files as 
converted by Donna.  Hooked it into the build system so they are only
built when specifically asked for, and when doing "make dist".

They're not perfect;  in particular, there are the following problems:
- The plain-text FAQ should be built from FAQ.xml, but this is not
  currently done.  (The text FAQ has been left in for now.)

- The PS/PDF building doesn't work -- it fails with an incomprehensible
  error message which I haven't yet deciphered.

Nonetheless, I'm putting it in so others can see it.

61fcb2828d Gave VG_(do_syscall)() a more specific prototype: 
Int VG_(do_syscall) ( UInt, UWord, UWord, UWord, UWord, UWord, UWord );

to replace the previous:
  
  Int VG_(do_syscall) ( UInt, ... )

Reason being that sometimes you could get incorrect args passed, when
passing 32-bit ints on 64-bit platforms.  I also added macros
VG_(do_syscall[123456]) to make life easier, and converted all the
relevant calls.
