Clean up a few partial-class semantics.

Fixes test-357.cs and cs1618-2.cs.
* cs-parser.jay (struct_declaration): Use 'current_class' as
parent of newly-created struct.  Remove call to Register ().
Use 'pop_current_class' to complete handing the current struct.
(interface_declaration): Likewise.
(class_declaration): Likewise.
(enum_declaration): Use 'current_class' as parent of newly created
enum.
(delegate_declaration): Likewise.
(pop_current_class): New function.  This is used to handle closing
up the 'current_class' and 'current_container', and pointing them
to the enclosing class/container.
(CSharpParser): Initialize 'current_class' too.
 decl.cs (MemberCore): Add check for invariant: a partial
container is not a parsed entity, and thus does not enclose any
parsed members.
(DeclSpace.TypeResolveEmitContext): Expose 'type_resolve_ec'.
(DeclSpace.BaseTypeExpr): Use it.
(DeclSpace.LookupType): Add check for invariant.
* class.cs (TypeContainer): Add check for invariant: a nested
class should have the same NamespaceEntry as its enclosing class.
(TypeContainer.EmitFieldInitializers): Make virtual.
(TypeContainer.DefineDefaultConstructor): Adhere to invariant in
MemberCore.
(TypeContainer.Register): Remove.
(TypeContainer.DefineType): Set the 'ec' of a PartialContainer to
null.  Use TypeResolveEmitContext for resolving base types and
interfaces.  Move initialization of Parts.TypeBuilder here from
...
(TypeContainer.DefineNestedTypes): ... here.
(PartialContainer): Take a Namespace not a NamespaceEntry.
(PartialContainer.Create): Don't use Register.  Call the
appropriate Add... function directly.
(ClassPart): Take both the PartialContainer and the enclosing
class as constructor arguments.
(ClassPart.EmitFieldInitializers): Override.
(ClassPart.PartFindNestedTypes): Remove.
(FieldBase.GetInitializerExpression): Resolve the initializer
expression in the emit context of the enclosing class.
* tree.cs (RootTypes): Remove Register ().
