Ghostwrite for many more names

[Zac-HD]

Closes #3311, which lists the tables that I worked off to write this function. We now guess strategies for 16,758,972 (8.43%) of 198,892,807 total arguments - excluding the staggeringly common (96,322,728) self argument which Hypothesis should never need to generate.

I actually feel pretty good about this: almost nine percent of all arguments is a pretty big win, and I think that the table below shows these are "reasonable guesses" that users will understand, even if they're not correct in all cases.

Table of all most-common arguments, with guessed strategy (if any)
