Introduce TLS descriptors for i386 and x86_64.
* include/inline-hashtab.h: New file, copied from 2005's
libiberty, with fix for memory leak imported afterwards by
Glauber de Oliveira Costa.
* elf/tlsdeschtab.h: New file.
* elf/dl-reloc.c (_dl_try_allocate_static_tls): Extract from...
(_dl_allocate_static_tls): ... here. Rearrange failure path.
(CHECK_STATIC_TLS): Move to...
* elf/dynamic-link.h: ... this file.
(TRY_STATIC_TLS): New macro.
* elf/dl-conflict.c (CHECK_STATIC_TLS, TRY_STATIC_TLS): Override.
* elf/elf.h (R_386_TLS_GOTDESC, R_386_TLS_DESC_CALL,
R_386_TLS_DESC): Define.
(R_X86_64_PC64, R_X86_GOTOFF64, R_X86_64_GOTPC32): Merge from
binutils.
(R_X86_64_GOTPC32_TLSDESC, R_X86_64_TLSDESC_CALL,
R_X86_64_TLSDESC): Define.
(R_386_NUM, R_X86_64_NUM): Adjust.
* sysdeps/i386/Makefile (sysdep-dl-routines, sysdep_routines,
systep-rtld-routines): Add tlsdesc and dl-tlsdesc for elf subdir.
(gen-as-const-headers): Add tlsdesc.sym to csu subdir.
* sysdeps/i386/dl-lookupcfg.h: New file. Introduce _dl_unmap to
release tlsdesc_table.
* sysdeps/i386/dl-machine.h: Include dl-tlsdesc.h.
(elf_machine_type_class): Mark R_386_TLS_DESC as PLT class.
(elf_machine_rel): Handle R_386_TLS_DESC.
(elf_machine_rela): Likewise.
(elf_machine_lazy_rel): Likewise.
(elf_machine_lazy_rela): Likewise.
* sysdeps/i386/dl-tls.h (struct dl_tls_index): Name it.
* sysdeps/i386/dl-tlsdesc.S: New file.
* sysdeps/i386/dl-tlsdesc.h: New file.
* sysdeps/i386/tlsdesc.c: New file.
* sysdeps/i386/tlsdesc.sym: New file.
* sysdeps/i386/bits/linkmap.h (struct link_map_machine): Add
tlsdesc_table.
* sysdeps/x86_64/Makefile (sysdep-dl-routines, sysdep_routines,
systep-rtld-routines): Add tlsdesc and dl-tlsdesc for elf subdir.
(gen-as-const-headers): Add tlsdesc.sym to csu subdir.
* sysdeps/x86_64/dl-lookupcfg.h: New file. Introduce _dl_unmap to
release tlsdesc_table.
* sysdeps/x86_64/dl-machine.h: Include dl-tlsdesc.h.
(elf_machine_runtime_setup): Set up lazy TLSDESC GOT entry.
(elf_machine_type_class): Mark R_X86_64_TLSDESC as PLT class.
(elf_machine_rel): Handle R_X86_64_TLSDESC.
(elf_machine_rela): Likewise.
(elf_machine_lazy_rel): Likewise.
* sysdeps/x86_64/dl-tls.h (struct dl_tls_index): Name it.
(__tls_get_addr): Do not declare for non-shared compiles.
* sysdeps/x86_64/dl-tlsdesc.S: New file.
* sysdeps/x86_64/dl-tlsdesc.h: New file.
* sysdeps/x86_64/tlsdesc.c: New file.
* sysdeps/x86_64/tlsdesc.sym: New file.
* sysdeps/x86_64/bits/linkmap.h (struct link_map_machine): Add
tlsdesc_table for both 32- and 64-bit structs.
