f3eb3bba16 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.
- Added support for Thumb2 :lower16: and :upper16: fix up.
- Added :upper16: and :lower16: relocation support to mach-o object writer.

82caf1a867 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.

7597212abc 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.

86a97f2e4d 1. Support ELF pcrel relocations for movw/movt: 
R_ARM_MOVT_PREL and R_ARM_MOVW_PREL_NC.
2. Fix minor bug in ARMAsmPrinter - treat bitfield flag as a bitfield, not an enum.
3. Add support for 3 new elf section types (no-ops)

62b83b62f3 Layout one section until no relaxations are done and then move to the next 
section.

This helps because in practice sections form a dag with debug sections pointing
to text sections. Finishing up the text sections first makes the debug section
relaxation trivial.

175fb36f10 Thumb's forced-PC-alignment requirement applies to the _total_ displacement, not just to the fragment relative 
portion.  While the fragment boundary is usually already aligned, it is possible for it not to be, which 
would lead to a non-aligned final displacement.

b87422778c 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).

   we don't need to worry about compatibility.
