d03033c19f Fix decoding of 64-bit values on 32-bit hosts. Improve register decoding speed
by more than 2x, aka use a big switch/tree to lookup the register ID from string.

3f15f4ed26 64-bit Mach exceptions support. Note that mach_exc_server() et al. must be
explicitly generated from mig. The advantage of that is to provide a "fast"
path for x86_64 on Leopard too (fault address in code[1]).

By "fast", this means +33% faster wrt. explicitly thread_get_state() but
still pretty slow (40 usec/fault). This is on par with the i386 code path though.

3615be1d4d Use fixed-size integer types, especially for 64-bit quantities. HP-UX for IPF
is essentially an ILP32 platform but machine registers are 64-bit wide. Make
IA64_SET_GR() set the NaT bit at the same time as the register value.

ef39e46cb2 Fix build on MacOS X Leopard.
Leopard kernel faster? This is pure marketing hype. For 32-bit applications,
Mach exception recovery is 60% slower. For 64-bit applications, this is up
to 40% faster though. In any case, MacOS X remains pretty slow wrt. Linux...

b1fa25128a Make it possible to override the Mach fault recovery scheme through an
environment variable: SIGSEGV_MACH_FAULT. It can be set to "direct" to
assume the fault address comes from code[1] argument, or "slow" to use
the slow path through thread_get_status(EXCEPTION_STATE)->faultvaddr.

58ff9aba45 The Linux kernel actually allows to restart execution from the specified slot
in the bundle. This is faster and more accurate as this avoids emulation.

Also clean-up code so that to prepare the use of lib uaccess on hpux/ia64.
XXX: this will need explicit use of uint64_t to define registers because
HP/UX is ILP32 capable and all registers are 64-bit capable so "unsigned long"
won't fit.

57ae6ed470 Add initial support for instruction skipping on Linux/ia64. It was more
complex than expected but it was fun to play with. Who designed this ISA?
I'd love to see how the decoder is implemented in HW, by all means it is
not "simplified" unless I missed some pattern...

9fa1bbd972 According to kernel sources, that is XNU 344.49 (10.2.8), XNU 517.12.7 (10.3.9),
XNU 792.21.3 (10.4.10) and XNU 1228 (10.5.0), exception handler code[1] always
contains the fault address nowadays. So make it the default fast path but keep
provisions to check that at run-time first.

This yields a nearly 4x improvement in SIGSEGV recovery but MacOS X is still
suboptimal wrt. Linux, so VOSF is still not possible with frameskip == 0.

XXX: the ppc kernel had bugs that caused DAR (put into code[1]) to be incorrectly
decoded. This would need a broader test audience or more careful audit of the
sources changes.
