pcpa 89f1e2f608 Properly split instruction groups for predicate registers. 
* include/lightning/jit_ia64.h, include/lightning/jit_private.h,
	lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c,
	lib/lightning.c: Rework code to detect need of a "stop" to
	also handle predicates, as if a predicate is written, it
	cannot be read in the same instruction group.
	  Use a single jit_regset_t variable for all registers when
	checking need for a stop (increment value by 128 for
	float registers).
	  Correct wrong "subi" implementation, as the code executed
	is r0=im-r1, not r0=r1-im.
	  Use standard lightning 6 fpr registers, and rework to
	use callee save float registers, that may be spill/reloaded
	in prolog/epilog. This is required because some jit
	instructions implementations need to call functions; currently
	integer div/mod and float sqrt, what may change the value of
	scratch float registers.
	  Rework point of "sync" of branches that need to return a
	patch'able address, because the need for a "stop" before a
	predicate read causes all branches to be the instruction
	in slot 0, as there is no template to "stop" and branch
	in the same instruction "bundle".

GNU lightning is a library to aid in making portable programs
that compile assembly code at run time.  For more information,
look at the info documentation.
