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

[Xiang Zhang via Phabricator via llvm-commits]

xiangzhangllvm added a comment.

And for "AssertZext ", both following DAG optimizations and ISel will try generate node/MIR to clear its high N bits to zero. ISel will directly ignore it.

  (I think it make sense, because it is just a flag/mark, it means its operand's high N bits already be 0)
