x86: Remove __memset_zero_constant_len_parameter [BZ #21790]
__memset_zero_constant_len_parameter should be removed by
commit 61062f56304750c367c5c1533351621353c112a7

* debug/Versions (libc: GLIBC_2.4): Remove
__memset_zero_constant_len_parameter.
* sysdeps/generic/memset_chk.c: Remove alias and warning.
* misc/sys/cdefs.h (__warndecl): New macro.
* debug/warning-nop.c: New file.
* string/bits/string3.h (memset): Call __warn_memset_zero_len
with no
arguments, instead of calling
__memset_zero_constant_len_parameter.
Use __warndecl for __warn_memset_zero_len.
* debug/Makefile (routines): Add $(static-only-routines).
(static-only-routines): New variable.
This patch removes the last emaining pieces of it. Tested it on i586,
i686 and x86-64.
[BZ #21790]
* sysdeps/i386/i586/memset.S
(__memset_zero_constant_len_parameter): Removed.
