Martin Schwidefsky 1ace5fcb22 s390: extend expoline to BC instructions ...

[ Upstream commit 6deaa3bbca804b2a3627fd685f75de64da7be535 ]

The BPF JIT uses a 'b <disp>(%r<x>)' instruction in the definition
of the sk_load_word and sk_load_half functions.

Add support for branch-on-condition instructions contained in the
thunk code of an expoline.
