Rename TypeOfExpr / TypeOfInst to MetatypeExpr / MetatypeInst. Introduce a '.metatype' form in the syntax and do some basic type-checking that I probably haven't done right. Change IR-generation for that and GetMetatypeExpr to use code that actually honors the dynamic type of an expression. Swift SVN r3053
