[PATCH] D11844: [Modules] More descriptive diagnostics for misplaced import directive

Fixed module boundary treatment.

This version must fix problems in the treatment of  annot_modulbegin and
annot_module_end. Error recover for the token annot_module_include found
in wrong context can be made as previously, just by ignoring it. To handle
token 'annot_module_end' parser bails out to upper level, where the module
end can be processed, it will complain on missing '}' etc. As for
'annot_module_start', now parser tries to recover by skipping all content
till matching 'annot_module_end'.

Also made changes according to reviewer's notes.
