One issue is that we turned (sizetype)(j + -1) * 4 to
((sizetype) j + 1073741823) * 4 which makes CSE of j + -1 difficult.

I have sent a patch that excludes the test from ilp32 targets, until
implementing a solution for this

We've just deprecated that, mind (doesn't negate that it could affect

This is optimized in x86 using -m32 during "combine", the problem is that the
test cases check for the optimization in GIMPLE. But, this isn't the case for
AArch64 using ILP32, which isn't optimiz

I implemented Andrew's suggested solution and sent it to the lists

Our team will also be busy with other priorities for the next weeks.
We will attempt to schedule this before the end of stage 1, but might still
have to delay until stage 3.

For LP64 (including using long), fre1 is able to optimize it.
ILP32 (with long rather than int):
```
k_12 = j_11(D) + -1;
j.0_1 = (sizetype) j_11(D);
_2 = j.0_1 + 1073741823;
_3 = _2 * 4;
_4 = a_
