VM treats instantiated function types with NumParentTypeArguments() != 0
as non-instantiated (as they potentially depend on the numbering of
enclosing type parameters) and would explicitly instantiate such types.
So bytecode generator needs to make sure that instantiated types,
instantiated type arguments and types used in constants always have
NumParentTypeArguments() == 0, so they would not need unnecessary
instantiation.

The analyzer already has a class with the same name, but a slightly
different purpose. (The analyzer's class represents a single message
associated with a source location, whereas the CFE's class represents
a message along with related context messages).
I'm currently embarking on an arc of work that I hope will eventually
culminate in unifying the analyzer and CFE diagnostic message
representations into a single set of classes. Until that unification
is complete, both representations will have to co-exist in the
`_fe_analyzer_shared` package. To reduce confusion during that time
period, I would like the classes to have distinct names.
Since the analyzer's `DiagnosticMessage` class is exposed through the
analyzer public API, analyzer clients may depend on the name. So it
makes sense to rename the CFE's `DiagnosticMessage` class.

Avoid caching generic types C<T1,...,Tn> in the object table if
any of type arguments T1,...,Tn are not cacheable.
Otherwise, bytecode reader might create function type
'C<Y0> Function<Y0>()' where cached type 'C<Y0>' references parameter
type Y0 which belongs to a wrong owner, such as another function type
'C<Y0> Function<Y0>(int)'.
Also, fix equivalence of default values of function type parameters
in case matching 'null' (meaning all dynamic) and '[dynamic, ..., dynamic]'.
This may happen during canonicalization before '[dynamic, ..., dynamic]'
type arguments are replaced with 'null'.

In this CL methods StructuralParameterType.forAlphaRenaming,
StructuralParameterType.forAlphaRenamingFromTypeParameter,
TypeParameterType.forAlphaRenaming, and
TypeParameterType.forAlphaRenamingFromStructuralParameter are removed,
and their call sites are replaced with invocations of other
constructors of StructuralParameterType and TypeParameterType. The
reason for this change is call sites having more information for
correct computing of type nullabilities.
In addition to the primary update, the following related changes are
made in this CL.
* Method StructuralParameterType.computeDefaultNullabilityForLibrary
is renamed into StructuralParameterType.computeDefaultNullability,
and TypeParameterType.computeDefaultNullabilityForLibrary is renamed
into TypeParameterType.computeDefaultNullability. The parameter
`library` is removed from both methods, since it's no longer needed.
* The static methods named `computeNullabilityFromBound` are removed
from `StructuralParameterType` and `TypeParameterType` and
re-introduced as instance members in classes `StructuralParameter`
and `TestParameter` respectively
