[Bug debug/31230] debug information depends on gc parameters

I can reproduce the problem using the provided testcase.

It looks like all we have to do is mark the array type TYPE_DOMAIN as used, to
prevent it from being garbage collected.  This just requires adding an
equate_type_number_to_die call, which should be harmless by itself, I think. 
This  solves the problem for the provided testcase.  I haven't done a bootstrap
or gdb testsuite run to test the patch yet.

It might be nice to try to reuse this info, via lookup_type_die, now that we
have saved it.  Unfortunately, the dwarf3 standard doesn't have any provision
for this.
