 /*
  * Set up a sequence of staggered jumps, forwards and backwards with

  * JITed native jumps. On some architectures, for example MIPS, a large
  * PC-relative jump offset may overflow the immediate field of the native
  * conditional branch instruction, triggering a conversion to use an
  * absolute jump instead. Since this changes the jump offsets, another
  * offset computation pass is necessary, and that may in turn trigger
  * another branch conversion. This jump sequence is particularly nasty
  * in that regard.
  *
  * The sequence generation is parameterized by size and jump type.
