+ (folding_cxx_constexpr): New variable.
+ (address_compare): Restrict the decl vs. STRING_CST
+ or vice versa or STRING_CST vs. STRING_CST or
+ is_global_var != is_global_var optimizations to !folding_cxx_constexpr.
+ Punt for FUNCTION_DECLs with non-zero offsets. If folding_initializer,
+ assume non-aliased functions have non-zero size and have different
+ addresses. For folding_cxx_constexpr, punt on comparisons of start
+ of some object and end of another one, regardless whether it is a decl
+ or string literal. Also punt for folding_cxx_constexpr on
+ STRING_CST vs. STRING_CST comparisons if the two literals could be
+ overlapping.

+ * decl2.cc (mark_used): Directly synthesize a DECL_MAYBE_DELETED
+ fn by calling maybe_synthesize_method instead of relying on
+ maybe_instantiate_noexcept. Move call to m_i_n after the
+ DECL_DELETED_FN handling.
+ * pt.cc (maybe_instantiate_noexcept): Restrict DECL_MAYBE_DELETED
+ fn synthesis to only those with an implicit noexcept-spec, and
+ return !DECL_DELETED_FN instead of !DECL_MAYBE_DELETED afterwards.
