Completed :lower16: / :upper16: support for movw / movt pairs on Darwin.

- Fixed :upper16: fix up routine. It should be shifting down the top 16 bits first.

Relax an assertion. On archs like ARM, an immediate field may be scattered. So it's possible for some bits of every 8 bits to be encoded already, and the rest still needs to be fixed up.

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.
