72f91cad26 [SystemZ] make test immune to scalarization improvements; NFC
The undef operands mean this test is probably still too fragile
to accomplish what the comments suggest.

cebc088508 [SelectionDAG] Handle big endian target BITCAST in computeKnownBits()
The BITCAST handling in computeKnownBits() previously only worked for little
endian.

This patch reverses the iteration over elements for a big endian target which
allows this to work in this case also.

SystemZ test case.
