again but only after the high registers are exhausted or (and this is
the important point) if they are explicitly requested.
Also, don't use r8 as it confuses things as we can't tell an explicit
request from a generic request for a byte register.

from register names when generating the clobber list as gcc won't
recognise things like r8d but will recognise r8.
This allows us to use the high number integer registers for the tests
which is something Julian asked for ages ago.

which are x86 specific. The first three x86 specific ones should
work on amd64 as well so I have added those as amd64 tests.
Note that the x86/amd64 tests will still fail as VEX doesn't
always trigger the right sort of signal for faulting instructions
at the moment.

normally give execute permission to memory allocated from the heap
with sbrk.
This also required fixing the smc1 test for amd64 to use mmap to
allocate memory so that it can have execute permission.

attempt to flush out any register-number bugs that might be lurking.
It would be nice to be able to do the same with the integer registers,
but gcc-3.3.4 is too stupid to understand asms with clobbered
registers "r8d", etc (plain "r8" etc is OK) and I am too ignorant of
perl to know how to mash r8b/r8w/r8d back into plain "r8" etc for the
clobbered registers list.

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.
