[When an explicit MODULE procedure is defined in the same (sub)module
as its interface, and the interface was defined in a generic
interface of the same name, bogus errors about symbols already
having been defined will ensue.  Cleaning up this aspect of name
resolution and symbol table management requires marking the
place-holding SubprogramNameDetails symbols of explicit MODULE
subprograms as such, ensuring that that attribute is not inherited
if the SubprogramNameDetails symbol is recycled as a SubprogramDetails,
and gathering some code that should have been common between
BeginSubprogram() and BeginMpSubprogram() together in one
new routine.
