    * options.h (class General_options): Add --ctors-in-init-array.

    friends as SHT_PROGBITS for merging sections.
    (Layout::layout): Remove special handling of .init_array and
    friends.  Don't sort if doing relocatable link.  Sort for .ctors
    and .dtors if ctors_in_init_array.
    (Layout::make_output_section): Force correct section types for
    .init_array and friends.  Don't sort if doing relocatable link,

    (Output_section::Input_section_sort_init_fini_compare::operator()):
    Handle .ctors and .dtors.  Sort by explicit priority rather than
    by name.
