Reapply r143202, with a manual decoding hook for SWP. This change inadvertantly exposed a decoding ambiguity between SWP and CPS that the auto-generated decoder can't handle.

Replace the existing ARM disassembler with a new one based on the FixedLenDecoderEmitter.
...
This new disassembler can correctly decode all the testcases that the old one did, though
some "expected failure" testcases are XFAIL'd for now because it is not (yet) as strict in
operand checking as the old one was.

Remove these two test files as they cause llvm-i686-linux-vg_leak build to fail 'test-llvm'.
...
These two are test cases which should result in 'invalid instruction encoding' from running llvm-mc -disassemble.

Add comments to the handling of opcode CPS3p to reject invalid instruction encoding,
...
a test case of invalid CPS3p encoding and one for invalid VLDMSDB due to regs out of range.
