[Bug rtl-optimization/40667] [4.4/4.5 Regression] stack frames are generated even with -fomit-frame-pointer

Because you need to decide whether to use a frame pointer or not before
register allocation, and only during/after register allocation you can find out
that something needs to be spilled to stack.
