Update code to build and pass test cases in the arm port.

Browse source 
* configure.ac, include/lightning/jit_private.h, lib/jit_arm-cpu.c,
	lib/jit_arm-swf.c, lib/jit_arm.c, check/Makefile.am: Correct
	implementation of the arm backend port to build and pass the
	current test cases. Tested on armv7 with softfp abi.

	* lib/jit_disasm.c: Rename and change prototype of static
	disassemble function as in the arm backend it is required
	to access state information stored in the jit_state_t object.

	* check/3to2.tst, check/add.tst: Correct test case code assuming
	JIT_RO and JIT_RET are the same, and even if they are the same,
	the logic was incorrect because it must always call jit_retval*
	to fetch a function call return before any other instruction.
	The arm backend hash a special condition if jit_retval is not
	called, because "r0" is not JIT_R0, but is JIT_RET and *also*
	the first argument for a called function, so JIT_RET must be
	only used as an argument to jit_retval.

	* TODO: New file listing important tasks to be resolved.
