[AArch64] Interpreter and c1 don't correctly handle jboolean results in native calls

The handlers for jboolean on Aarch64 are incorrect. This can lead to wrong results being passed as return values from native calls which return jboolean values if these values are not exactly '1' or '0' (i.e. a return value of '2' will be interpreted as 'false').
This is a dup of bug 8209637.
