UCLO JIT

* Checks that there are no upvalues to be closed in given trace
* Eliminate UCLO completely if that is the case

This assumes that upvalues state is consistent across each trace

(empirical results indicate that this is indeed the case,
but there might be some ugly corner cases).

This results in rather dramatic speedup of closure-heavy code
(see tests/clobench.lua). Next up: FNEW
