Add the new jit_pointer_p predicate interface.

Browse source 
* include/lightning.h, lib/lightning.c: Add the new
	jit_pointer_p interface, that returns a boolean value
	telling if the pointer argument is inside the jit
	code buffer. This is useful to avoid the need to add
	extra labels and calls to jit_address to figure bounds
	of code buffer, and still keep internal data private.
