[Bug c++/23708] Non-inline function incorrectly treated as inline when using precompiled headers

["jconner at apple dot com" <gcc-bugzilla@gcc.gnu.org>]

When generating a precompiled header, finish_member_declaration() invokes note_decl_for_pch() for 
the function "testfn<T>", and assigns it to the COMDAT section with weak linkage.

Then, when the test.C file is compiled, a function "testfn<int> (implicit declaration)" is generated, and 
inherits the COMDAT properties of "testfn<T>".  Finally, when the explicit specialization is actually 
seen, the function duplicate_decls() attempts to merge the declarations, and assigns the specialization 
function (incorrectly) to the COMDAT section.

When not using precompiled headers, the "testfn<T>" function is not assigned to the COMDAT section 
until after its attributes are merged with the specialization by duplicate_decls(), and since checks are 
already in place to make sure that the specialization doesn't inherit the DECL_DECLARED_INLINE_P 
attribute (which is a prerequesite for ending up in COMDAT), both decls are assigned to the correct 
sections.
