arReserve() uses a really stupid quadratic algorithm for allocating chunks larger than 8 bytes. It should use something smarter.

A simple proposal for removing the isEmptyRange usage in AR::reserveEntry, using the where an non-empty slot is found to calculate how far to shift the search window. No changes outside of AR::reserveEntry needed, perf results look reasonable.

Nanojit has been dead for several years. Its Bugzilla component has been moved to the graveyard (bug 984276). I checked all the open bugs. They're all uninteresting, so I'm WONTFIXing them all. Apologies for the bugspam.
