Rollup merge of #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 ```
