PowerPC64 __tls_get_addr_desc
This implements register saving and restoring in the __tls_get_addr call stub, so that when glibc supports the optimized tls call stub gcc can generate code that assumes only r0, r12 and of course r3 are changed on a __tls_get_addr call. When gcc expects __tls_get_addr calls to preserve registers the call will be to __tls_get_addr_desc, which will be translated by the linker to a call to __tls_get_addr_opt. bfd/ * elf64-ppc.h (struct ppc64_elf_params): Add no_tls_get_addr_regsave. * elf64-ppc.c (struct ppc_link_hash_table): Add tga_desc and tga_desc_fd.

(ppc64_elf_tls_setup): Set up tga_desc and tga_desc_fd. Indirect tga_desc_fd to opt_fd, and tga_desc to opt. Set no_tls_get_addr_regsave. (branch_reloc_hash_match): Add hash3 and hash4.
