Correct logic error with jit_live in jit_retr

* lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c: Correct wrong logic in usage of jit_live in jit_retr. The problem is that if a temporary is required during epilog, the return register might be allocated, so, jit_live must always be used.
