* ipa.c (function_and_variable_visibility): Decompose DECL_ONE_ONLY
groups when we know they are controlled by LTO.
* varasm.c (default_binds_local_p_1): If object is in other partition,
it will be resolved locally.
* lto-partition.c (get_symbol_class): Only unforced DECL_ONE_ONLY
needs duplicating, not generic COMDAT.
