8ab17244a8 Add VGP_(setup_redirects) to the platform specific layers and use
it to setup vsyscall redirects on amd64 and the _dl_sysinfo_int80
redirect on x86.

ba4f330105 Build the arch, os and platform libraries as PIE code if PIE is
enabled as they get linked into stage2 which is the PIE part.

61c97ea72d Clear next AMD64 startup hurdle. Required copying the x86 LDT code.
Not sure if it's the right thing to do long-term, but good enough for
now.

10b4595add Added beginnings of an AMD64 port, so lots of new files and directories.
It compiles, but aborts immediately if you try to run it.

I didn't include ldt.c;  I'm not sure how the LDT is used on AMD64.  It can be
added later if necessary.

While doing this, did some 64-bit cleanness fixes:
- Added necessary intermediate casts to ULong to avoid warnings when converting
  ThreadId to void* and vice versa, in vg_scheduler.c.
- Fixed VALGRIND_NON_SIMD_CALL[0123] to use 'long' as the return type.
- Fixed VALGRIND_PRINTF{,BACKTRACE} to use unsigned longs instead of unsigned
  ints, as needed.
- Converted some offsets in vg_symtab2.h from "Int" to "OffT".
- Made strlen, strncat, etc, use SizeT instead of 'unsigned int' for the length
  parameter.
- Couple of other minor things.

I had to insert some "#ifdef __amd64__" and "#ifndef __amd64__" guards in
places.  In particular, in vg_mylibc.c, some of our syscall wrappers aren't
appropriate for AMD64 because the syscall numbering is a bit different in
places.  This difference will have to be abstracted out somehow.

Also rewrote the sys_fcntl and sys_fcntl64 wrappers, as required for AMD64.

Also moved the ipc wrapper into x86, since it's not applicable for
AMD64.  However, it is applicable (I think) for ARM, so it would be nice
to work out a way to share syscall wrappers between some, but not all,
archs.  Hmm.  Also now using the real IPC constants rather than magic
numbers in the wrapper.

Other non-AMD64-related fixes:
- ARM: fixed syscall table by accounting for the fact that syscall
  numbers don't start at 0, but rather at 0x900000.
- Converted a few places to use ThreadId instead of 'int' or 'Int' for
  thread IDs.
- Added both AMD64 and ARM (which I'd forgotten) entries to valgrind.spec.in.
- Tweaked comments in various places.
