Initial attack at basic 'class' feature

Adds a new experimental warning, feature, keywords and enough parsing to
implement basic classes with an empty `new` constructor method.

Inject a $self lexical into method bodies; populate it with the object instance, suitably shifted
Creates a new OP_METHSTART opcode to perform method setup
Define an aux flag to remark which stashes are classes

Basic implementation of fields.

Basic anonymous methods.
