TIntermFunctionDefinition nodes now have a TIntermFunctionPrototype
child that stores the function signature, instead of having a separate
type and an aggregate child that stores the parameters.

This makes parsing functions simpler, and paves the way for further
simplifications of function parsing, like reducing conversions between
symbol table structures and AST structures.

TIntermAggregate is now only used for function calls.
