Merge #607
607: Remove split-stack from backend r=tschwinge a=dkm
From Mark Wielaard : https://gcc.gnu.org/pipermail/gcc-rust/2021-August/000110.html
> The backend was derived from the go backend which enables split stack
> support by default. This inserts a __morestack call at the start of
> each function. This is not needed for the rust backend. Remove the
> split stack support code from the rust backend and spec.
