the type is PT_TLS.

GNU hash table if they need a dynamic value. Otherwise, don't add
them if they are defined in a dynamic object or are forced local.

regular and a dynamic object only needs a dynamic symbol table
entry if it is externally visible.

is_entsize_zero_.

before updating section flags. Set entsize.

and SHF_STRING if all input sections have those flags.

sections.

relaxed input sections.

return type to Output_relaxed_input_section pointer. Adjust code
for new type of relaxed_input_section_map_.
