Add basic Itanium port infrastructure.

Browse source 
* include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c,
	lib/jit_ia64-fpu.c, lib/jit_ia64.c: New files implementing
	the basic infrastructure of an Itanium port. The code
	compiles and can generate jit for basic hello world like
	functions.

	* check/lightning.c, configure.ac, include/lightning.h,
	include/lightning/Makefile.am, include/lightning/jit_private.h,
	lib/Makefile.am, lib/lightning.c: Update for the Itanium
	port.

	* lib/jit_mips-cpu.c, lib/jit_mips.c: Correct typo and
	make the jit_carry register local to the jit_state_t.
	This matches code reviewed in the Itanium port, that
	should use the same base logic to handle carry/borrow.
