Remove unnecessary ClassLiteral name member and simplify Function.name handling

Remove unnecessary ClassLiteral name member and simplify Function.name handling

A class's name is its constructor's name, so there's no need to treat it separately,
either in the parser or in code generation. The main parser use of the name is
for ES2015 Function.name handling, and this patch also cleans up handling there
by adding a new IsAnonymousFunctionDefinition() method to Expression (the name
comes from the spec).

Also removed unused ParserTraits::DefaultConstructor method.

rossberg: please look at the parser/ast changes
