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.

portion. While the fragment boundary is usually already aligned, it is possible for it not to be, which

MC/Mach-O: On second thought, use a custom hook for enabling aggressive

IsSymbolRefDifferenceFullyResolved, it turns out this does change behavior on
enough cases for x86-32 that I would rather wait a bit on it.
- In practice, we will want to change this eventually because it only means we
generate less relocations (it also eliminates the need for the horrible
'.set' hack that Darwin requires in some places).
