Rollup merge of #146732 - durin42:llvm-22-less-assumes, r=nikic 
tests: relax expectations after llvm change 902ddda120a5

LLVM 22 is able to drop assumes that seem to not help further optimizations, which actually seems to dramatically _help_ further optimizations in some of our small test cases.

I'm a little unclear how to fix the last failure, in `tests/codegen-llvm/issues/issue-122600-ptr-discriminant-update.rs`:

```
-; Function Attrs: mustprogress nofree norecurse nosync nounwind willreturn memory(argmem: readwrite, inaccessiblemem: write) uwtable
+; Function Attrs: mustprogress nofree norecurse nosync nounwind nonlazybind willreturn memory(argmem: readwrite, inaccessiblemem: write) uwtable
 define void ``@update(ptr`` noundef captures(none) %s) unnamed_addr #0 {
 start:
-  %_3.sroa.0.0.copyload = load i8, ptr %s, align 1
-  %0 = trunc nuw i8 %_3.sroa.0.0.copyload to i1
-  %1 = xor i1 %0, true
-  tail call void ``@llvm.assume(i1`` %1)
   store i8 1, ptr %s, align 1
   ret void
 }
```

I'm just not conversant enough in LLVM IR to follow the changes here.
