It's well known that char is faster than string of length 1.

This rule should detect whether it's possible to use char version of string.
Many examples can be found inside String class.

e.g.

Prefer

string.IndexOf ('x');

over

string.IndexOf ("x");


I believe this rule can be pretty generic if possible, but at least String
methods are a must.
