Re apply 130577 narrow math for and operand (#133896)
Re-apply https://github.com/llvm/llvm-project/pull/130577
Which is reverted in https://github.com/llvm/llvm-project/pull/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.
