Have Program::IsValid() return false unless built

An unbuilt program doesn't have an ast::Module, so Program::AST() will just explode.

* Have a Program default to false for IsValid()
* Initialize the ast_ field to nullptr. This was previously floating.
* Return from CommonFuzzer::Run() earlier if the InputFormat is not recognised.
