URL: https://github.com/llvm/llvm-project/commit/fb2bdbb83d3913d9d32b28c1de3f3d8b4e6dfc8a DIFF: https://github.com/llvm/llvm-project/commit/fb2bdbb83d3913d9d32b28c1de3f3d8b4e6dfc8a.diff LOG: [CodeGen] Avoid use of ConstantExpr::getZExt() (NFC) Use the constant folding API instead. In preparation for dropping zext constant expressions.
