Update.

	* sysdeps/generic/strchr.c: Include <memcopy.h> and use reg_char
	for character to search, to help the compiler.
	* sysdeps/generic/strchrnul.c: Likewise.
	* sysdeps/generic/memchr.c: Likewise.
	* sysdeps/generic/memccpy.c: Likewise.
	* sysdeps/generic/rawmemchr.c: Likewise.  Fix comment.
