* elf32-sh.c (elf_sh_link_hash_entry): Replace

* elf32-sh.c (elf_sh_link_hash_entry): Replace
datalabel_got_offset with union of datalabel_got
offset and refcount.
(sh_elf_link_hash_newfunc): Initialize datalabel_got.refcount.
(allocate_dynrelocs): Delete unnecessary code for
STT_DATALABEL type.  Create entry in got for
datalabel version of symbol if datalabel_got.refcount > 0.
(sh_elf_relocate_section): Use datalabel_got union.
(sh_elf_gc_sweep_hook): Pull common code to initialize
h and eh out of switch statement.  Declare seen_stt_datalabel.
Initialize it.  Decrement datalabel_got.refcount for
got relocs when seen_stt_datalabel is true.
Decrement local_got_refcounts entry for datalabel got relocs
of local symbols.
(sh_elf_copy_indirect_symbol): Copy datalabel_got field over.
(sh_elf_check_relocs): Declare seen_stt_datalabel.
Initialize it.  When seen_stt_datalabel is true, increment
datalabel_got refcount rather than got.refcount.
(sh_elf_finish_dynamic_symbol): Create relocs to
initialize got entry for datalabel version of symbol.
