Add tests for w/ writeback instruction parsing and encoding.

In addition to improving the representation, this adds support for assembly
parsing of these instructions.

r0 = mov #0
r0 = moveq #1

Then the second instruction has an implicit data dependency on the first
instruction. Sadly I have yet to come up with a small test case that
demonstrate the post-ra scheduler taking advantage of this.

Work in progress. Parsing for non-writeback, single spaced register lists
works now. The rest have the representations better factored, but still
need more to be able to parse properly.

point to ARC-managed pointers sometimes. This fixes rdar://10551239.

emission is not supported yet, but a patch that adds the support should follow
soon.

When 'cmp rn #imm' doesn't match due to the immediate not being representable,
but 'cmn rn, #-imm' does match, use the latter in place of the former, as
it's equivalent.

  to finalize MI bundles (i.e. add BUNDLE instruction and computing register def
  and use lists of the BUNDLE instruction) and a pass to unpack bundles.
- Teach more of MachineBasic and MachineInstr methods to be bundle aware.
- Switch Thumb2 IT block to MI bundles and delete the hazard recognizer hack to
  prevent IT blocks from being broken apart.

[asan] remove .preinit_array from the compiler module (it breaks .so builds). This should be done in the run-time.
