[PATCH] D106053: [CodeGen] Remove pending AssertZext AssertSext in promoting FP_TO_INT

[Eli Friedman via Phabricator via llvm-commits]

To be clear, I'm working on the assumption that AssertZext means "if the operand is not poison, the high N bits are not set".  I'm not sure we've formally stated that anywhere, but I think it's consistent with how SelectionDAG optimizations use AssertZext in practice.
