BUG: Fix overflow warning on apple silicon - #18571

@isuruf, I know that did not work in gh-18555 which may actually just be the identical issue?

Before we add more clang workaround, can you make sure to compiling with -ffp-exception-behavior=strict? We have to make that flag default on clang and make sure to not add any workarounds for clang bugs that are actually just bad compiler defaults.

I am not on top of these efforts here, so ignore if this is obviously unhelpful...

-ffp-exception-behavior=strict

The exception is still there if I add that flag without this PR.

The one PyPy failure seems unrelated:

TypeError: __format__() missing 1 required positional argument: 'spec'

Let's see if there's more opinions on a preference of this PR vs. gh-17712. I'd be inclined to merge this one.

I think this would be fine. I think my solution on #17712 would be a bit cleaner (and have the advantage of unifying the code path of single-value and vector computations), but I was stymied by the time taken to make it work with the 128-bit code path. This is certainly a simpler and more direct solution.
