Implement fpr register arguments and minor extra fixes.

Browse source 
* include/lightning.h: Add new backend specific movr_w_d,
	movr_d_w and movi_d_w codes as helpers to ia64 varargs
	functions arguments.

	* lib/jit_ia64-cpu.c:
	  Correct wrong encoding of A5 small integers.
	  Correct define of "mux" instruction modifiers.
	  Correct ordering of arguments and predicates of cmp_xy
	implementation with immediate arguments; like most other
	codes with an immediate, the immediate is the second, not
	the third argument.

	* lib/jit_ia64-fpu.c: Actual implementation of the code
	to move to/from gpr to/from fpr, to implement varargs abi.

	* lib/jit_ia64.c: Make fpr argument registers not allocatable
	as temporaries, no need for the extra checks when there are
	plenty registers.

	* lib/jit_print.c, lib/lightning.c: Minor updates for the
	new movr_w_d, movr_d_w and movi_d_w codes.
