[flang] Process SeparateModuleSubprogram during name resolution

When a SeparateModuleSubprogram is encountered, check that there is a
corresponding declaration in the current module/submodule or an ancestor.
When it's the current program unit, special handling is required to
avoid trying to declare it again.

Module subprograms with the `MODULE` prefix are handled similarly.
The `hasModulePrefix` flag is passed in to `BeginSubprogram` to
distinguish this case.

Extract common part of `Post(SubroutineStmt)` and `Post(FunctionStmt)` into
`PostSubprogramStmt`. Add code there to ensure that separate module
procedures do not have `EXTERNAL` set. This requires a fix to `ModFileWriter`
to correctly decide when a subprogram is declared in an interface block.

Extract `WalkSubprogramPart` into a separate function. It walks the
internal or module subprograms collecting their names. It is needed to
handle separate module subprograms.

[flang] Fix bug in rewriting function reference

`a(i)` is parsed as a function reference and needs to be converted to an
array element reference when `a` is an object entity. That determination
was wrong if the symbol for `a` was a symbol representing host-association
or use-association. In that case we need to get to the original symbol
by calling `GetUltimate()` on the symbol.

This was causing symbol09.f90 to get a compilation error because an
array element reference looked like a call to a non-pure function, which
is prohibited inside a DO CONCURRENT.

[flang] More name resolution for construct entities

Push a new scope for constructs and statements that require one
(DataStmt, DO CONCURRENT, ForallConstruct, ForallStmt -- there are more
to do). Currently we use the Block kind of scope because there is no
difference. Perhaps that kind should be renamed to Construct, though it
does apply to statements as well as constructs.

Add DeclareConstructEntity to create a construct or statement entity.
When the type is not specified it can come from the type of a symbol in
the enclosing scope with the same name. Change DeclareObjectEntity et al.
to return the symbol declared, for the benefit of DeclareConstructEntity.

Use DeclareConstructEntity for DO CONCURRENT index-name, LOCAL, and
LOCAL_INIT variables and the data-i-do-variable in DataImpliedDo

Names in SHARED locality spec need special handling: create a new kinds
of symbol with HostAssocDetails to represent the host-association of the
shared variables within the construct scope. That symbol gets the
LocalityShared flag without affecting the symbol in the outer scope.
HostAssoc symbols may be useful in other contexts, e.g. up-level
references to local variables.

Add parser::DoConstruct::IsDoConcurrent() because DO CONCURRENT loops
introduce a construct scope while other DO loops do not.

Move CanonicalizeDo to before name resolution so that name resolution
doesn't have to deal with labeled DO CONCURRENT loops.

Allow for type of index name to be specified in ConcurrentHeader.

[flang] More miscellaneous name resolution

Resolve the index name in a FORALL, DO, or DO CONCURRENT.

Handle pointer-stmt. Add DeclareUnknownEntity() to declare an entity
that is not yet know to be an object or procedure. This is used in the
EntityDecl and PointerDecl cases.

When an array element assignment is mistakenly parsed as a statement
function, ensure the index names are resolved.

Detect erroneous use-association with local name that matches the name
of the containing subprogram.

Cleanup: Eliminate GetVariableName() and CheckImplicitSymbol() in favor
of using the Resolve* functions consistently. Add ResolveName() to do
what CheckImplicitSymbol() used to do.

Disable warnings about unresolved names for some categories of
constructs that are not yet implemented: common blocks, namelist
statements, etc. These will be turned back on when they are implemented.

[flang] Check conflicting construct names

Check that construct names don't conflict with other construct names or
entities in the same scoping unit.

This requires adding symbols for them. MiscDetails was added for cases
like this where we don't need to save much information about the symbol.
References to construct names are recorded too, so those names are now
expected to be resolved and no longer are exceptions in rewrite-parse-tree.cc

Checking that construct names match is still done in resolve-labels.cc.
