Detect and emit errors when names are redefined in the same scope, e.g.

the info. Also, call Actions.ParseParamDeclaratorType instead of
Actions.ParseDeclarator for parameter type lists: we don't want declaration
objects created when parsing a function declarator, we just want type info.

parameters: build an array of ParamInfo structures and pass it to the
declarator for safe keeping (it owns the list).
Next step: actually populate the arg array with useful stuff.

fundamentally requires having an AST around, so move all sema to the
AST library. This is the first step, later steps will be needed to
clean up libast.
