CVS commit: src/common/lib/libc/arch/arm/string
Module Name: src
Committed By: matt

Make this work on all ARMs but keep the armv6 optimizations. It as fast as
the existing strlen for small string and once strings are 8 bytes or more in
length it starts getting significantly faster. For really long strings,
compared to the existing strlen, this uses about 1/2 of the cycles for the
non-armv6 version and about 1/3 of the cycles for the armv6 version.
