	(NOP, CROR_151515, CROR_313131, TP_OFFSET, DTP_OFFSET): Define.
	(struct ppc_elf_link_hash_entry): Rename "root" to "elf".  Adjust uses.

	(struct ppc_elf_link_hash_table): Rename "root" to "elf".  Adjust uses.
	Add got, relgot, plt, relplt, dynbss, relbss, dynsbss, relsbss,
	sdata, sdata2, tls_sec, tls_get_addr, tlsld_got fields.
	Make use of htab shortcuts throughout file.
	(ppc_elf_link_hash_newfunc): Init tls_mask field.

	(update_local_sym_info, bad_shared_reloc): New functions.

	entries and got relocs here.  Warn on non-zero got reloc addend.
	Split out branch taken/not taken reloc code into a separate switch
	and correct offset calculation. Allow BRTAKEN/BRNTAKEN dynamic relocs.
	Split out HA reloc adjustments to separate switch statement.  Don't
	warn on reloc overflow if we've already warned about undefined.
