This patch refactor ARM memchr ifunc selector to a C implementation.
No functional change is expected, including ifunc resolution rules.

It also reorganize the ifunc options code:

  1. The memchr_impl.S is renamed to memchr_neon.S and multiple
     compilation options (which route to armv6t2/memchr one) is
     removed.  The code to build if __ARM_NEON__ is defined is
     also simplified.

  2. A memchr_noneon is added (which as build along previous ifunc
     resolution) and includes the armv6t2 direct.

  3. Same as 2. for loader object.

Alongside the aforementioned changes, it also some cleanus:

  - Internal memchr definition (__GI_memcpy) is now a hidden
    symbol.
  - No need to create hidden definition for the ifunc variants.

Checked on armv7-linux-gnueabihf and with a build for arm-linux-gnueabi,
arm-linux-gnueabihf with and without multiarch support and with both
GCC 7.1 and GCC mainline.

	* sysdeps/arm/armv7/multiarch/Makefile [$(subdir) = string]

This patch refactor ARM memcpy ifunc selector to a C implementation.
No functional change is expected, including ifunc resolution rules.

It also adds some cleanup:

  - Internal memcpy hidden definition (__GI_memcpy) is now a hidden
    symbol.

  - No need to create hidden definition for the ifunc variants.

Checked on armv7-linux-gnueabihf and with a build for arm-linux-gnueabi,
arm-linux-gnueabihf with and without multiarch support and with both
GCC 7.1 and GCC mainline.  I also checked with the some possible
multiarch different configurations that trigger different memcpy
buids (__ARM_NEON__ && !__SOFT_FP__, !__ARM_NEON__ && !__SOFT_FP__, and
!__ARM_NEON__ && __SOFT_FP__).

This patch provides an optimised implementation of memchr using NEON
instructions to improve its performance, especially with longer search regions.
This gave an improvement in performance against the Thumb2+DSP optimised code,
with more significant gains for larger inputs. The NEON code also wins in cases
where the input is small (less than 8 bytes) by defaulting to a simple
byte-by-byte search. This avoids the overhead imposed by filling two quadword
registers from memory.

	* sysdeps/arm/armv7/multiarch/Makefile: Add memchr_neon to
	sysdep_routines.
	* sysdeps/arm/armv7/multiarch/ifunc-impl-list.c: Add define for
	__memchr_neon.
	Add ifunc definitions for __memchr_neon and __memchr_noneon.
	* sysdeps/arm/armv7/multiarch/memchr.S: New file.
	* sysdeps/arm/armv7/multiarch/memchr_impl.S: Likewise.
	* sysdeps/arm/armv7/multiarch/memchr_neon.S: Likewise.

Testing done: Ran regression tests for arm-none-linux-gnueabihf as well as a
full toolchain bootstrap. Benchmark tests were ran on ARMv7-A and ARMv8-A
hardware targets.

This semi-mechanical patch removes all uses and definitions of the
sfi_breg, sfi_pld, and sfi_sp macros from various ARM-specific
assembly files.  These were only used by NaCl.

	* sysdeps/arm/sysdep.h
        (ARM_SFI_MACROS, sfi_breg, sfi_pld, sfi_sp): Delete definitions.

	* sysdeps/arm/__longjmp.S, sysdeps/arm/add_n.S

	* sysdeps/arm/strlen.S, sysdeps/arm/submul_1.S:
        Remove all uses of sfi_breg, sfi_pld, and sfi_sp.

The default required version of binutils has been increased to 2.22
making this check redundant.
