PR middle-end/36282
* c-pragma.c (apply_pragma_weak): Only look at
TREE_SYMBOL_REFERENCED (DECL_ASSEMBLER_NAME (decl)) if
DECL_ASSEMBLER_NAME_SET_P (decl).
(maybe_apply_pending_pragma_weaks): Exit early if
vec_safe_is_empty (pending_weaks) rather than only when
!pending_weaks.
(maybe_apply_pragma_weak): Likewise.  If !DECL_ASSEMBLER_NAME_SET_P,
set assembler name back to NULL afterwards.
