* config/ia64/sysdepCallMethod.h (sysdepCallMethod): Fix to really
match register passing conventions. Only the first eigth parameter
slots are passed in registers. This concerns both integer and
floating-point values.

* config/ia64/linux/md.h (COMPARE_AND_EXCHANGE): Move to...
* config/ia64/common.h: ... here.

The Intel Itanium Processor-specific ABI defines
__sync_bool_compare_and_swap primitive (7.4.3).

* config/config-setjmp.h (JTHREAD_DECLARE_JMPBUF,
JTHREAD_ACCESS_JMPBUF): Kill.
* kaffe/kaffevm/exception.c (dispatchException): Likewise.
* kaffe/kaffevm/exception.h (vmExcept_jumpToHandler): Likewise.
* kaffe/kaffevm/jni.c (BEGIN_EXCEPTION_HANDLING*): Likewise.

Instead, the jthread struct containing a jmp_buf must be aligned
once it is allocated. Other occurrences were already aligned per
natural alignment requirements in stack.

* config/ia64/linux/md.c (IA64_context_*): Update to match current
state-threads v1.4 code from SGI.

* config/ia64/sysdepCallMethod.h (sysdepCallMethod): Really match
calling conventions. We now can deal with a mix of ints, longs,
floats and doubles correctly. Reindent.

* kaffe/kaffevm/systems/unix-jthreads/jthread.c
(JTHREAD_CONTEXT_SAVE, JTHREAD_CONTEXT_RESTORE): New macros
specific to context switches.
(newThreadCtx): Align jthread struct on 16-byte boundaries for
jmp_buf. Move down stack adjusting.
