Jonas Paulsson 9b4875434e [SystemZ] Updated test fp-cast.ll 
This did not get included in the previous commit for SystemZ cost functions.

llvm-svn: 300053

Jonas Paulsson fccc7d66c3 [SystemZ] TargetTransformInfo cost functions implemented. 
getArithmeticInstrCost(), getShuffleCost(), getCastInstrCost(),
getCmpSelInstrCost(), getVectorInstrCost(), getMemoryOpCost(),
getInterleavedMemoryOpCost() implemented.

Interleaved access vectorization enabled.

BasicTTIImpl::getCastInstrCost() improved to check for legal extending loads,
in which case the cost of the z/sext instruction becomes 0.

Review: Ulrich Weigand, Renato Golin.
