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.

* match.c (gfc_match_common): Use gfc_match_common_name instead
of match_common_name.
* match.h : Rename match_common_name to gfc_match_common_name.
* resolve.c (resolve_common_vars): Check each symbol in a
common block has a global symbol. If there is a global symbol
issue an error if the symbol type is a module or a program.
