Various fixes to the eBPF JIT for powerpc, thanks to some new tests
added by Johan. This series fixes all failures in test_bpf on powerpc64.
There are still some failures on powerpc32 to be looked into.

Great work! I have tested it on powerpc64 in QEMU, which is the same
setup that previously triggered an illegal instruction, and all tests
pass now. On powerpc32 there are still some issues left as you say.

Thanks for the review, and the test!
