add native a_crash primitive for arm

the .byte directive encodes a guaranteed-undefined instruction, the
same one Linux fills the kuser helper page with when it's disabled.
the udf mnemonic and and .insn directives are not supported by old
binutils versions, and larger-than-byte integer directives would
produce the wrong output on big-endian.
