Add a second pass to compute live register ranges

Browse source 
* include/lightning/jit_private.h, lib/lightning.c: Add a
	second pass from start when computing register live ranges.
	This should be used temporarily, and is required for certain
	loop constructs, with several consecutive blocks not referencing
	a live register.
