Re-apply #130577 Which is reverted in #133880 The old application failed in address sanitizer due to `tryNarrowMathIfNoOverflow` was called after `I.eraseFromParent();` in `AMDGPUCodeGenPrepareImpl::visitBinaryOperator`, it create a use after free failure. To fix this, `tryNarrowMathIfNoOverflow` will be called before and directly return if `tryNarrowMathIfNoOverflow` result in true.
