ExtensionTypeMemberDescriptor.memberReference and
ExtensionMemberDescriptor.memberReference are now nullable.
TFA-based tree shaker can now set them to null when extension type
member is not used and removed but corresponding lowered tear-off is
still used and retained.
Front-end never sets them to null and requires non-null memberReferences
when consuming kernel.

This is used for instance in the lowering for handling duplicate writes

Previously we would encode the type of the value returned in `async`
functions as the field `futureValueType` on `FunctionNode`. For all
other kinds of functions, such as `sync`, `sync*`, and `async*`, that
field would be null. This CL renames `futureValueType` into
`emittedVAlueType`, and for functions of kinds `async`, `sync*`, and
`async*` that is expected to be the type of values emitted via
`return` or `yield` statements. For `sync` functions that field is
supposed to contain `null`.

This CL introduces StructuralParameter and StructuralParameterType
classes. They are intended to replace TypeParameter and
TypeParameterType respectively where those were used as type
parameters defined by FunctionTypes. Previously, type parameters of
FunctionTypes were represented by TypeParameter objects with the
‘parent’ field set to null. By introducing StructuralParameter and
StructuralParameterType this CL unambiguously separates the two
notions of type parameters.
