Idea is to save work for GHC. Instead of having >>= as type class method for some polymorphic `m` we work in ST which GHC knows how to compile and optimize very well. No changes to exposed API Reduces allocation during compilation of Data.Vector.Generic.Mutable by ~20%. No measurable changes in other modules
