Subject: Remove sfi_* annotations from ARM assembly files.

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/addmul_1.S, sysdeps/arm/arm-mcount.S
	* sysdeps/arm/armv6/rawmemchr.S, sysdeps/arm/armv6/strchr.S
	* sysdeps/arm/armv6/strcpy.S, sysdeps/arm/armv6/strlen.S
	* sysdeps/arm/armv6/strrchr.S, sysdeps/arm/armv6t2/memchr.S
	* sysdeps/arm/armv6t2/strlen.S
	* sysdeps/arm/armv7/multiarch/memcpy_impl.S
	* sysdeps/arm/armv7/strcmp.S, sysdeps/arm/dl-tlsdesc.S
	* sysdeps/arm/memcpy.S, sysdeps/arm/memmove.S
	* sysdeps/arm/memset.S, sysdeps/arm/setjmp.S
	* sysdeps/arm/strlen.S, sysdeps/arm/submul_1.S:
        Remove all uses of sfi_breg, sfi_pld, and sfi_sp.
