Method defer_trap

cranelift/codegen/src/machinst/buffer.rs:1300–1308

Emit a trap at some point in the future with the specified code and stack map. This function returns a [`MachLabel`] which will be the future address of the trap. Jumps should refer to this label, likely by using the [`MachBuffer::use_label_at_offset`] method, to get a relocation patched in once the address of the trap is known. This will batch all traps into the end of the function.
