Do we need faster regex?

[Richard (Rikki) Andrew Cattermole]

The tables are stored compressed.

We do that because otherwise the binary size of Phobos would grow by 
multiple megabytes (think 10, not 1).

This is why when you trigger usage of regex at CT it slows down a whole 
lot. One of my optimizations was to prevent this unless it was needed.

However there are a lot of templates in use in each of the tables, and 
these could all be swapped out for something else and I think that might 
shave off something close to 100ms.

The tradeoffs for the tables are good ones, but it does bite us a bit here.
