Sanjay Patel a44dc32708 [SystemZ] make test immune to scalarization improvements; NFC

Jonas Paulsson e9f7fa83d5 [SelectionDAG] Handle big endian target BITCAST in computeKnownBits() 
The BITCAST handling in computeKnownBits() previously only worked for little

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

SystemZ test case.
