Optimise the layout of the `RE2` class.

In particular, `error_arg_` should be a pointer... that will almost
always be `empty_string`. Also, separate the relatively cold fields
from the relatively hot fields to be slightly friendlier to caches.

Bump SONAME accordingly.

Credit and gratitude to Clement Courbet for his suggestions.
