I think it would be better to use a dedicated branch for the stable release. Otherwise we'll backport quite a few changes (the LLVM 22.1.7 and LLVM 22.1.8 releases).

Add regression test for enum miscompilation
eabe5e4
@workingjubilee@Mark-Simulacrum
Revert "Only exclude the 155473 change for 1-byte bool-likes"
e641fea
This reverts commit 569ad99.
The PR widened the effect of this from enums with the 0..=1 range to
those with any range if they had more than 1 byte.
Unfortunately, our LLVMIR now incurs miscompilations, so revert until
we find a better fix.

Backport fix for 159035
979b2d3
This backports more than just the small fix as the original base has
moved on main too.
