Add testing of generated (ARM) baseline decoders using hand-written decoders.

Add testing of generated (ARM) baseline decoders using hand-written decoders.

This testing allows us to prove that the generate and hand-written decoders
behave the same way (for the inputs that use the hand-written decoders).
As a result, once tests pass, we can replace the corresponding hand-written
decoders with the generated decoders.

Note: This CL only compares baseline decoders in the data_processing_register
ARM table.

PTAL. Thanks.

Note: All but one of the test files are only changed by the inclusion of file
baseline_vs_baseline.h.

// op1(24:20)=10001 & $pattern(31:0)=xxxxxxxxxxxxxxxx0000xxxxxxxxxxxx
Note: This is the only test file that has any real changes. The other test files
only include the new header file:
baseline_vs_baseline.h
