debug/101533 - ICE with variant typedef DIE generation
There's a sanity check in gen_type_die_with_usage that trips
unnecessarily for a case where the relevant DIE has already been
generated successfully in other ways. The following keys the
existing TREE_ASM_WRITTEN check on the correct object, honoring
this and does nothing instead of ICEing for the testcase at hand.
PR debug/101533
* dwarf2out.cc (gen_type_die_with_usage): When we have
output the typedef already do nothing for a typedef variant.
Do not set TREE_ASM_WRITTEN on the type.
* g++.dg/debug/pr101533.C: New testcase.
