* config.h.in (HAVE_AVX2_SUPPORT): New #undef.
* sysdeps/i386/configure.ac: Set HAVE_AVX2_SUPPORT and
config-cflags-avx2.
* sysdeps/x86_64/configure.ac: Likewise.
* sysdeps/i386/configure: Regenerated.
* sysdeps/x86_64/configure: Likewise.
* sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add
memset-avx2 only if config-cflags-avx2 is yes.
* sysdeps/x86_64/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list):
Tests for memset_chk and memset only if HAVE_AVX2_SUPPORT is
defined.

This patch moves the USE_REGPARMS define from the toplevel
configure.ac to sysdeps/i386/configure.ac.
Tested x86 that the disassembly of installed shared libraries is
unchanged by this patch.
* configure.ac (USE_REGPARMS): Don't define here.
* configure: Regenerated.
* sysdeps/i386/configure.ac (USE_REGPARMS): Define here.
* sysdeps/i386/configure: Regenerated.
Autoconf has been deprecating configure.in for quite a long time.
Rename all our configure.in and preconfigure.in files to .ac.
