[cfe] Refactor bounds checking
This CL moves the bounds checking into the TypeBuilder instead of
performing it from the outside on the computed DartType node.
This solves several problems:
1) Errors are now reported on the type in the code instead of the
declaration which holds the type.
2) Checking of type aliases (both function and nonfunction type
aliases) is now handled correctly in all cases. This achieved by
computed the aliased type (containing TypedefType nodes)
internally and performing the checking on this type, and only
convert the type into the unaliased version (without TypedefType
nodes) after checks have been performed. Previously this handled
through the FunctionType.typedefType property for function type
aliases and through and incomplete work-around for nonfunction
type aliases.
3) With 2) FunctionType.typedefType is no longer needed and is
removed.
