arm: Start to remove the now unneeded acle-compat.h

All supported compilers provide the acle macros so we don't need the
backup versions.

Keep the file around for anything that included it directly

Stop using __FreeBSD_ARCH_armv6__ and switch to __ARM_ARCH >= 6 in the
couple of places in tree. clang already implements ACLE. Add a define
that says we implement version 1.1, even though the implementation
isn't quite complete.
