* Add static flag -fsimple-list-literals
The new static flag -fsimple-list-literals makes ExplicitList literals
be desugared in the straightforward way, rather than using 'build' as
now. See SLPJ comments with Note [Desugaring explicit lists].
I don't expect this flag to be used by users (hence no docs). It's just
there to let me try the performance effects of switching on and off.
