Before D126061 <https://reviews.llvm.org/D126061>, Clang would warn about this code

  struct X {
      [[deprecated]] struct Y {};

with the warning

  attribute 'deprecated' is ignored, place it after "struct" to apply attribute to type declaration

D126061 <https://reviews.llvm.org/D126061> inadvertently caused this warning to no longer be emitted. This patch
restores the previous behavior.

The reason for the bug is that after D126061 <https://reviews.llvm.org/D126061>, C++11 attributes applied to a
member declaration are no longer placed in `DS.getAttributes()` but are instead
tracked in a separate list (`DeclAttrs`). In the case of a free-standing
decl-specifier-seq, we would simply ignore the contents of this list. Instead,
we now pass the list on to `Sema::ParsedFreeStandingDeclSpec()` so that it can
issue the appropriate warning.
