Relax slightly the existing check for diagnosing a bare CTAD placeholder
as the return type of a function declarator to also handle the abstract
declarator case.
gcc/cp/ChangeLog:
* decl.cc (grokdeclarator): Diagnose a CTAD placeholder as
function return type even when !funcdecl_p.
gcc/testsuite/ChangeLog:
* g++.dg/other/pr88187.C: Adjust expected C++17 diagnostic.
