PR fortran/95707 - ICE in finish_equivalences, at fortran/trans-common.c:1319

With submodules and equivalence declarations, name mangling may result in
long internal symbols overflowing internal buffers.  We now check that
we do not exceed the enlarged buffer sizes.

PR fortran/95707
* gfortran.h (gfc_common_head): Enlarge buffer.
* trans-common.c (gfc_sym_mangled_common_id): Enlarge temporary
buffers, and add check on length on mangled name to prevent
overflow.
