Hal Finkel 2345347eb9 Add a disassembler to the PowerPC backend ...

The tests for the disassembler were adapted from the encoder tests, and for the
most part, the output from the disassembler matches that encoder-test inputs.
There are some places where more-informative mnemonics could be produced
(notably for the branch instructions), and those cases are noted in the tests
with FIXMEs.

Future work includes:

 - Generating more-informative mnemonics when possible (this may also be done
   in the printer).

 - Remove the dependence on positional "numbered" operand-to-variable mapping
   (for both encoding and decoding).

 - Internally using 64-bit instruction variants in 64-bit mode (if this turns
   out to matter).
