Add new --enable-devel-disassembler configure option

	lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c: Add a new
	--enable-devel-disassembler option, that should be used
	during development, or lightning debug. This option
	intermixes previous jit_print and jit_disassemble
	output, making it easier to visualize what lightning
	call was used, and what code was generated.
