* output.cc: Rename Output_data_got template parameter from size to got_size for all functions. Compile all variants of Output_data_got. (Output_data_got::Got_entry::write): Correct use of size for symbol value. Use local_is_tls rather than casting to Sized_relobj_file. * object.h (class Object): Add local_is_tls and do_local_is_tls. (class Sized_relobj_file): Add do_local_is_tls. * incremental.h (class Sized_relobj_incr): Add do_local_is_tls.
