Tim Keith 86726d8ee4 [flang] Continue work on name resolution 
Enhance DeclTypeSpecVisitor to find derived-type-specs, including with
type parameter values.

Change DerivedTypeSpec so it only needs the name of the derived type,
not the definition, as that isn't necessarily known when we encounter
it.

Fix how memory is managed in DeclTypeSpec: Intrinsic type specs aren't a
problem -- they are one of a few types that live throughout the program.
Derived type specs are dynamically allocated and the memory is owned by
the DeclTypeSpec -- it allocates it when a DeclTypeSpec for a derived
type is created and deletes it when it is destroyed. Pass around
references to TypeSpecs rather than pointers as they can never be null.

In AttrsVisitor, DeclTypeSpecVisitor, ResolveNamesVisitor: make most
functions out-of-line to clean up the class declaration.

In AttrsVisitor, use preprocessor to simplify the simple case of
encountering a parse-tree class causing an attribute to be set.
Handle all such attributes.

Remove old testing code from type.cc.

Remove some of the declarations for IntExpr and IntConst -- they are
only placeholder classes anyway. Don't distinguish kind and length
parameter values.

Tim Keith 9f755666fb [flang] Add ENUM_CLASS to define enum class with ToString function. 
This replaces DEFINE_NESTED_ENUM_CLASS in parse-tree.h but works
similarly. "ENUM_CLASS(Foo, A, B, C)" defined enum class Foo with
enumerators A, B, C. It also defines an overloading of EnumToString
that converts enumerators to their string representation.

Change unparse.cc to adapt to this change.

Make use of ENUM_CLASS in attr.h and attr.cc.
