507121f63f [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.

6778aa5c4f [flang] Fix failure to resolve submodule name. 
If we have `SUBMODULE(m:s1) s2` and `s1` is already in memory (i.e. does
not need to be read from the `m-s1.mod` file), we still need to record
the fact that the name is a reference to that module symbol.

ac0c599920 [flang] Fix bug with popping scopes. 
Processing a SUBMODULE can cause any number of scopes to be pushed on
the scope stack. We don't know how many to pop at the end, so add
`ClearScopes()` to reset the scope stack to its original state.

e064f4f4b9 [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.

object goes out of scope.

SemanticsContext is now the only state passed in to class ExprAnalyzer,
