* check/add.tst, check/allocai.tst, check/bp.tst, check/divi.tst, check/fib.tst, check/lightning.c, include/lightning/jit_arm.h, include/lightning/jit_mips.h, include/lightning/jit_ppc.h, include/lightning/jit_private.h, include/lightning/jit_x86.h: Make JIT_RET, JIT_FRET and JIT_SP private. These should not be used in any operations due to frequently having special constraints (usually JIT_FRET). JIT_FP must be made available because it must be used as the base register to access stack space allocated with jit_allocai.
