Static methods cannot be called during AST transformation via AstBuilder.buildFromSpec()

Static methods cannot be called during AST transformation via AstBuilder.buildFromSpec() because AstSpecificationCompiler.staticMethodCall() doesn't take a ClassNode object and if I try to call it with a Class object, I get "ClassNode#getTypeClass is called before the type class is set" error. I have no idea why the method takes a Class object instead.

I attached a program to reproduce the error. Please unzip the Test.zip and run Main.groovy then you'll get the following error:

Caught: BUG! exception in phase 'canonicalization' in source unit 'src\Main.groovy' ClassNode#getTypeClass for Clazz is called before the type class is set

I also attached a patch for the trunk to add a version that takes a ClassNode object.
