Model :upper16: and :lower16: as ARM specific MCTargetExpr. This is a step
...
in the right direction. It eliminated some hacks and will unblock codegen
work. But it's far from being done. It doesn't reject illegal expressions,
e.g. (FOO - :lower16:BAR). It also doesn't work in Thumb2 mode at all.

JimG sez: "The value-kinds look like masks, but they're not consistently used
...
that way, unfortunately. If you want to change them to work additively instead
of a one-variant-kind-per-symbolref, that's great and I completely agree it's
worth doing, but it really should be a separate patch. Until then, this isn't
correct."
So I am reverting this bit until a more opportune time.
