performance-faster-string-find

Optimize calls to std::string::find() and friends when the needle passed is a single character string literal. The character literal overload is more efficient.

By default only std::basic_string is considered. This list can be modified by passing a ; separated list of class names using the StringLikeClasses option. The methods to consired are fixed, though.

Examples:

str.find("A");

// becomes

str.find('A');
