ae3b96456f [flang] Simplify representation of intrinsic types 
Intrinsic types are now just a TypeCategory and a int kind. If no kind
is specified the default is used so that every type has an explicit
kind. This caused changes in the expected results of some of the tests.

Add support for "double precision" and "double complex".

Intrinsic types are now stored as values in DeclTypeSpec so none of the
KindedTypeHelper machinery is needed any more.

Eliminate DerivedTypeDef, DataComponentDef, ProcComponentDef,
TypeBoundProc. The components and bindings of a derived type are now
represented by the corresponding Scope.

7227cfe026 [flang] Miscellaneous name resolution 
Handle BIND statement and PARAMETER statement. They are different from
other attribute-setting statements so some refactoring of
HandleAttributeStmt is required. And for PARAMETER, SetType needs to
report an error if the implicitly determined type is changed later. This
requires operator== on DeclTypeSpec.

Resolve names in allocate statements, pointer assignment statements,
substring expressions, and type parameter values.

7ebbe7dca4 [flang] Write private symbols to .mod files 
We were trying to write only symbols that are part of the public API of
a module to the .mod file. The problem with that is that submodules need
access to the private symbols in their ancestor modules and submodules.

For now, just write out all of the symbols, private or otherwise.
We could be more precise by omitting some private symbols for modules
that don't have separate module procedures and so can't have submodules.

Also, the old implementation went into an infinite loop for recursive
derived types.

This makes CollectSymbols simpler, so have it do both the collecting and
sorting. Make it static so that the types don't have to be defined in
mod-file.h.

78c62eaf02 [flang] Ensure use of ObjectEntityDetails for data objects 
A symbol is created with EntityDetails if we don't know whether it is a
procedure or data object. At the end of the specification part, if we
don't know it's a procedure then it must be an object, so convert it
then. So after name resolution there should be no symbols with
EntityDetails.

Also, a couple of small fixes:
- need to visit sub-nodes of shape specs so that any names get resolved
- don't report an error for an array element mis-parsed as a call
