re PR c++/44059 (Static initializers executed more than once when using unique global symbols)
PR c++/44059
* config/elfos.h (ASM_DECLARE_OBJECT_NAME): Use qnu_unique_object
even for DECL_ONE_ONLY DECL_ARTIFICIAL !TREE_READONLY decls.
* config/alpha/elf.h (ASM_DECLARE_OBJECT_NAME): Likewise.
* dwarf2asm.c (dw2_output_indirect_constant_1): Set TREE_READONLY
on DW.ref.* decls.
