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.
