bpf/tests: Add staggered JMP and JMP32 tests
This patch adds a new type of jump test where the program jumps forwards and backwards with increasing offset. It mainly tests JITs where a relative jump may generate different JITed code depending on the offset size, read MIPS.

/*
|
||||
* 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.
