+ Implement fallback jit_mov{n,z}r. These are a somewhat cheap
+ implementation, but should be reviewed for the arches that already
+ have a proper conditional move.
+ * lib/jit_arm-sz.c, lib/jit_mips-sz.c: Add missing maximum size
+ estimative and reorder.
+ * lib/jit_aarch64-sz.c, lib/jit_x86-sz.c, lib/jit_ppc-sz.c:
+ Reorder entry to match definition order.

+ lib/jit_ia64-sz.c, lib/jit_riscv-sz.c, lib/jit_s390-sz.c,
+ lib/jit_sparc-sz.c: Add heuristic value, basically the sum of
+ the cost of a movr + beqr.
+ * lib/jit_names.c: Add entries for debug output of mov{n,z}r.
+ * lib/lightning.c: Use proper bitmask in jit_classify.

+ * include/lightning.h.in (jit_get_reg, jit_unget_reg): Expose the
+ macros in the public header file.
+ * include/lightning/jit_private.h (jit_get_reg, jit_unget_reg):
+ Remove the macros from the private header file.

+
+ * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement %rip relative
+ calls and jumps on x86_64. Currently very conservative, assuming
+ a jit block can be larger than 2G, so, if a jump or call is in
+ the same jit generation, but target is unknown, use an indirect
+ branch (could have an option to assume a jit code block is
+ never larger than 2G). Also a deoptimization is that now does
+ not always generate ip relative jmpi; previously implicitly
+ assumed jmpi would never be larger than 2G. Overall still an
+ optimization.

* lib/lightning.c: Add a proper fix to the condition of considering
to the set of registers to scan for live range, what might
consume a lot of cpu time, doing nothing.
