Matthew Flatt 16a0727231 optimizer: fix reordering in let+values+values splitting 
While the commit comment in 3150b31eb7 still seems right, the changed
overlooked the fact that the arguments to a split `values` might get
reordered (due to the way binding positions are calculated). Fix the
optimizer to make sure that reordering is allowed.

The change touches a lot of code, because we want to use
"omittable" to implement "movable", and it's not ok to
reorder access of mutable variables (in case some other thread is
mutating them). We have to fix all the calls to "omittable"
to support the slight generalization.
