This teaches DumpRegisterInfo to generate a table from the register
flags type. It just calls a method on RegisterFlags.

As such, the extra tests are minimal and only show that the intergration
works. Exhaustive formatting tests are done with RegisterFlags itself.

Example:

  (lldb) register info cpsr
         Name: cpsr
         Size: 4 bytes (32 bits)
      In sets: general (index 0)
  
  | 31 | 30 | 29 | 28 | 27-26 | 25  | 24  | 23  | 22  | 21 | 20 | 19-13 |  12  | 11-10 | 9 | 8 | 7 | 6 | 5 |  4  | 3-2 | 1 | 0  |
  |----|----|----|----|-------|-----|-----|-----|-----|----|----|-------|------|-------|---|---|---|---|---|-----|-----|---|----|
  | N  | Z  | C  | V  |       | TCO | DIT | UAO | PAN | SS | IL |       | SSBS |       | D | A | I | F |   | nRW | EL  |   | SP |

LLDB limits the max terminal width to 80 chars by default.
So to get that full width output you will need to change the "term-width"
setting to something higher.
