Implement new synthesized IR codes sequences

Browse source 
* lib/jit_rewind.c: New file implementing generic functions
	to "rewind", or rewrite IR code sequences.

	* include/lightning.h: Add several new codes, that previously
	were a function call, that would synthesize the operation.
	Now, there is a code for the operation, and a new flag to
	know an operation is synthesized.

	* include/lightning/jit_private.h: Add several new macros to
	help construct synthesized IR code sequences.

	* lib/Makefile.am: Update for lib/jit_rewind.c.

	* lib/jit_disasm.c: Update for a small rework on jit_node_t,
	so that --enable-devel-disassembler does not need a change
	in the layout of jit_node_t.

	* lib/jit_names.c: Update for the new codes.

	* lib/jit_print.c: Update to print more readable output, and
	flag synthesized IR code sequences.

	* lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
	lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_x86-sz.c,
	lib/jit_x86.c: Update for new synthesized IR code sequences.

	* lib/jit_ppc-cpu.c, lib/jit_ppc-fpu., lib/jit_ppc-sz.c,
	lib/jit_ppc.c, lib/jit_mips-cpu.c, lib/jit_mips-fpu.c,
	lib/jit_mips-sz.c, lib/jit_mips.c, lib/jit_s390-fpu.c,
	lib/jit_s390-sz.c, lib/jit_s390.c: Update for new synthesized
	IR code sequences and correct bugs in the initial varargs
	implementation support.

	* lib/jit_alpha-sz.c, lib/jit_alpha.c, lib/jit_hppa-sz.c,
	lib/jit_hppa.c, lib/jit_ia64-sz.c, lib/jit_ia64.c,
	lib/jit_sparc-sz.c, lib/jit_sparc.c: Add generic, untested
	support for the new synthesized	IR code sequences. Known
	most likely broken right now, and should be corrected once
	access to these hosts is available.

	* lib/lightning.c: Update for new IR codes, and add support
	for not yet existing instructions that change third argument.

	* size.c: Change to use different tables for LE and BE PowerPC.
	Correct a wrong endif for x32.
