* elf-bfd.h (struct elf_link_hash_entry): Add new field elf_hash_value.
	* elflink.h (elf_collect_hash_codes): New function.  This function is
	called for each exported symbol and we compute the ELF hash value for
	it.
	(compute_bucket_value): New function.  It is called from
	size_dynamic_sections to determine the hash table size.  When we are
	optimizing a better, but slower, algorithm is used.
	(size_dynamic_sections): Call compute_bucket_value.

	* elf.c (bfd_elf_hash): Optimize the hash function a bit.
