Martin Schwidefsky 63fd9d43c0 s390/lib: use expoline for all bcr instructions
commit 5eda25b10297684c1f46a14199ec00210f3c346e upstream.

The memove, memset, memcpy, __memset16, __memset32 and __memset64
function have an additional indirect return branch in form of a
"bzr" instruction. These need to use expolines as well.
