Fortran : ICE in build_field PR95614
Local identifiers can not be the same as a module name. Original
patch by Steve Kargl resulted in name clashes between common block
names and local identifiers. A local identifier can be the same as
a global identier if that identifier is not a module or a program.
The original patch was modified to reject global identifiers that
represent a module or a program.
