c++: DWARF ICE with defaulted specialization [PR90674]
Here when we merged the specialization with the implicit instantiation
declaration, we wrongly kept the value of DECL_INITIALIZED_IN_CLASS_P from
the latter.
gcc/cp/ChangeLog:
PR c++/90674
* decl.c (duplicate_decls): Don't propagate
DECL_INITIALIZED_IN_CLASS_P to a specialization.
gcc/testsuite/ChangeLog:
PR c++/90674
* g++.dg/debug/defaulted1.C: New test.
