string: Improve generic memchr

New algorithm have the following key differences:

  - Reads first word unaligned and use string-maskoff function to
    remove unwanted data.  This strategy follow assemble optimized
    ones for aarch64, powerpc and tile.

  - Use string-fz{b,i} and string-opthr functions.

Checked on x86_64-linux-gnu, i686-linux-gnu, sparc64-linux-gnu,
and sparcv9-linux-gnu by removing the arch-specific assembly
implementation and disabling multi-arch (it covers both LE and BE
for 64 and 32 bits).

	[BZ #5806]
	* string/memchr.c: Use string-fzb.h, string-fzi.h, string-opthr.h.
