* include/lightning.h, lib/jit_aarch64.c,
	lib/jit_alpha.c, lib/jit_arm-vfp.c, lib/jit_arm.c,
	lib/jit_hppa.c,	lib/jit_ia64.c, lib/jit_mips.c,
	lib/jit_ppc.c, lib/jit_s390.c, lib/jit_sparc.c,
	lib/jit_x86.c: Add the new jit_arg_register_p predicate.
	The predicate is expected to be used to know if an
	argument is in a register, what would need special
	handling if code that can overwrite non callee save
	registers is executed.

	* check/carg.c: New test case to check consistency and
	expected usage of jit_arg_register_p.

	* check/Makefile.am: Update for new test case.
