5615	ghc produces poor code for `div` with constant powers of 2.	Lennart	daniel.is.fischer	"The code for Int {{{(div x c)}}} where {{{c}}} is a constant of the form 2^n^ should be implemented with an arithmetic right shift, currently it's a call to a function.  This optimization should be done for all signed types.
