To summarize: we were trying to preserve the API that CodeString was providing, to avoid disruption. Turns out that (suggested by pmichaud) some of these methods are better located elsewhere; By splitting this out, we can just use StringBuilder (which now has an emit-like method) for combining PIR, add a single opcode (find_codepoint), and the rest of the methods are now baked into PCT. So, a few uses of CodeString in trunk were changed to StringBuilder, and that gives us basically the same speedup and memory improvement we were seeing in the branch. Thanks to everyone who hacked on these bits. There are still uses remaining of CodeString that can be updated; We're deprecating it to force folks to switch to the faster methods we'll be using in core.
