Unrolled build for rust-lang#131116

Rollup merge of rust-lang#131116 - mustartt:aix-stack-size, r=petrochenkov

Increase Stack Size for AIX

On AIX, there are limited support for tail call optimizations, so we need to set a larger stack size value.

Fixes the following tests on AIX:
```
[ui] tests/ui/associated-consts/issue-93775.rs
[ui] tests/ui/closures/deeply-nested_closures.rs
[ui] tests/ui/issues/issue-74564-if-expr-stack-overflow.rs
[ui] tests/ui/parser/survive-peano-lesson-queue.rs
```
