* varasm.c (output_constant_def_contents): For asan_protect_global
protected strings, adjust DECL_ALIGN if needed, before testing for
anchored symbols.
(place_block_symbol): Adjust size for asan protected STRING_CSTs if
TREE_CONSTANT_POOL_ADDRESS_P. Increase alignment for asan protected
normal decls.
(output_object_block): For asan protected decls, emit asan padding
after their contents.
* asan.c (asan_protect_global): Don't check TREE_ASM_WRITTEN here.
(asan_finish_file): Test it here instead.
