Rework to better describe what is used only during jit generation.

* include/lightning/jit_private.h, lib/jit_arm-cpu.c, lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips-cpu.c, lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc-cpu.c, lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c, lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c, lib/lightning.c: Add an extra structure for data storage during jit generation, and release it after generating jit, to reduce a bit memory usage, and also to make it easier to understand what data is available during jit runtime.
