Miscellaneous efficiency enhancements

Functions that have an empty prototype and that do nothing but return a fixed value are now inlined (e.g. sub PI () { 3.14159 }).

Each unique hash key is only allocated once, no matter how many hashes have an entry with that key. So even if you have 100 copies of the same hash, the hash keys never have to be reallocated.
