Jump optimizations may enable more push-pop elimination
Jump optimization replaces an unnecessary conditional jump, e.g.
`IFNULL l; l: ...` by `POP`, which enables further push-pop elimination.
Also introduces a `-YoptTrace` flag that traces the progress of the
bytecode as it goes through local optimizations.
