[mlir][math] Fix `math.powf` expansion case for `pow(x, 0)` (#119015)
Lowering `math.powf` to `llvm.intr.powf` will result in `pow(x, 0) =
1`, even for `x=0`. When using the Math dialect expansion patterns,
`pow(0, 0)` will result in `-nan`, however, This change adds two
additional instructions to the lowering to ensure the `pow(x, 0)` case
lowers to to `1` regardless of the value of `x`.
Resolves https://github.com/llvm/llvm-project/issues/118945.
