compiler: fix jump-threading regression.
* share/txr/stdlib/optimize.tl (basic-blocks
thread-jumps-block): We want a set here, not a pset, otherwise
we are processing the old-instruction again rather than
iterating. This breaks jump threading where multiple
iterations are required to get to the ultimate target. It
showed up as a difference in the compiled image of the
sys:compile-match function.
