* sysdeps/generic/libc-tls.c (__libc_setup_tls): Initialize the static
	slotinfo list's len member to the proper size, not just 1.
	Initialize static_map.l_tls_initimage.

	* elf/dl-open.c (dl_open_worker): Fix loop searching for
	dtv_slotinfo_list element containing new modules' l_tls_modid.

	* elf/tst-tls9.c, elf/tst-tls9-static.c: New files.
	* elf/tst-tlsmod5.c, elf/tst-tlsmod6.c: New files.
	* elf/Makefile (tests): Add tst-tls9.
	(tests-static): Add tst-tls9-static.
	(tst-tls9-static-ENV): New variable.
	($(objpfx)tst-tls9-static, $(objpfx)tst-tls9-static.out): New targets.

	* elf/dl-close.c (remove_slotinfo): Remove an assert; the number of
	modids used by partially loaded modules being closed can't be known.
