Subject: c-decl.c, [...]: Don't check TARGET_MEM_FUNCTIONS.

	* c-decl.c, config/m32r/m32r.c, expr.c, optabs.c: Don't check
	TARGET_MEM_FUNCTIONS.
	* system.h: Poison TARGET_MEM_FUNCTIONS.
	* libfuncs.h (LTI_bcopy, LTI_bcmp, LTI_bzero, bcopy_libfunc,
	bcmp_libfunc, bzero_libfunc): Remove.
	* optabs.c (init_obtabs): Don't set bcopy_libfunc, bcmp_libfunc or
	bzero_libfunc.
	* doc/tm.texi (TARGET_MEM_FUNCTIONS): Remove.
	* doc/standards.texi: Don't mention calling BSD string functions.
	* doc/invoke.texi: Likewise.  Mention that memmove may be called.
	* config/vax/t-memfuncs: New.
	* config/memcmp.c, config/memcpy.c, config/memmove.c,
	config/memset.c: New.
	* config/pdp11/t-pdp11 (LIB2FUNCS_EXTRA): Use these files.
	* config.gcc (vax-*-bsd*, vax-*-sysv*, vax-*-ultrix*): Use
	vax/t-memfuncs.
	* config/alpha/alpha.h, config/arc/arc.h, config/arm/arm.h,
	config/avr/avr.h, config/c4x/c4x.h, config/cris/aout.h,
	config/elfos.h, config/gnu.h, config/h8300/h8300.h,
	config/i386/gas.h, config/ia64/ia64.h, config/interix.h,
	config/ip2k/ip2k.h, config/lynx-ng.h, config/m32r/m32r.h,
	config/mcore/mcore.h, config/mips/mips.h, config/mmix/mmix.h,
	config/netbsd.h, config/openbsd.h, config/pa/pa.h,
	config/rs6000/rs6000.h, config/rtems.h, config/s390/s390.h,
	config/sh/sh.h, config/sparc/sparc.h, config/stormy16/stormy16.h,
	config/svr3.h: Don't define TARGET_MEM_FUNCTIONS.
