--- Comment #9 from Amara Emerson <aemerson at apple.com> ---
Huh, this is already fixed on trunk:

commit c2b322fc19e829162ed4c7dcd04d9e9b2cd4e66c
Author: Tim Northover <t.p.northover at gmail.com>
Date:   Mon Feb 1 12:43:33 2021 +0000

    GlobalISel: check type size before getZExtValue()ing it.

    Otherwise getZExtValue() asserts.

I've cherry-picked it to release/12.x in fa0971b87fb2
