Move emit and emit_safepoint to prelude.isle

Even though the implementation of emit and emit_safepoint may
be platform-specific, the interface ought to be common so that
other code in prelude.isle may safely call these constructors.

This patch moves the definition of emit (from all platforms)
and emit_safepoint (s390x only) to prelude.isle.  This required
adding an emit_safepoint implementation to aarch64 and x64 as
well - the latter is still a stub as special move mitosis
handling will be required.
