target/s390x: fix handling of zeroes in vfmin/vfmax
vfmin_res() / vfmax_res() are trying to check whether a and b are both
zeroes, but in reality they check that they are the same kind of zero.
This causes incorrect results when comparing positive and negative
zeroes.

target/s390x: fix NaN propagation rules
s390x has the same NaN propagation rules as ARM, and not as x86.

tests/tcg/s390x: test signed vfmin/vfmax
Add a test to prevent regressions. Try all floating point value sizes
and all combinations of floating point value classes. Verify the results
against PoP tables, which are represented as close to the original as
possible - this produces a lot of checkpatch complaints, but it seems
to be justified in this case.
