c++ modules: ICE with bitfield in class template
According to grokbitfield, DECL_BIT_FIELD_REPRESENTATIVE contains the
width of the bitfield until we layout the class type (after which it'll
contain a decl). Thus for a bitfield in a class template it'll always
be the width, and this patch makes us avoid ICEing from mark_class_def
in this case.
gcc/cp/ChangeLog:
* module.cc (trees_out::mark_class_def): Guard against
DECL_BIT_FIELD_REPRESENTATIVE not being a decl.
gcc/testsuite/ChangeLog:
* g++.dg/modules/bfield-3.H: New test.
