The scalar-default-character-expression that defines the interoperable
name of a function or subroutine (or interface) must have its names
resolved within the context of the subprogram, despite its appearance
on a function-stmt or a subroutine-stmt.  Failure to do so can lead
to bogus errors or to incorrect results.

The solution is to defer name resolution for function-stmt suffixes
(but not entry-stmt suffixes) and for subroutine-stmt language binding
specifications to EndSubprogram().  (Their resolution only need to be
deferred to the end of the specification part, but it's cleanest to
deal with it in EndSubprogram().)
