FIXME(#19497) -- Stop messing around and just give rustc 32MB of stack unconditionally. This is prompted by some sort of bug in trans that causes a stack overflow when the modules in trans are made private. (In particular, the overflow can also be avoided by making controlflow and callee public, but that seems strictly worse than just using more stack.)
