/*
* Set up a sequence of staggered jumps, forwards and backwards with
* increasing offset. This tests the conversion of relative jumps to
* 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.
* The size must be even, and the expected result is always size + 1.
* Below is an example with size=8 and result=9.
