Add new test case to check stack integrity on complex stack frames.

Browse source 
* check/stack.ok, check/stack.tst: New files to test data
	integrity on a deep chain of stack frames.

	* lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,
	lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
	lib/jit_x86.c, lib/jit_x86-cpu.c: Calculate _jit->function->stack
	in the emit stage, otherwise it will calculate it wrong if
	need to jit_allocai space to spill registers.

	* lib/lightning.c: Correct wrong offset when updating the
	"current" jit function pointer in the code that may need to
	allocate stack space to spill registers.

	* check/lightning.c: Correct off by one data space check.

	* check/Makefile.am: Update for new test case.
