gas/ppc: Additional tests for DFP instructions
I noticed that some of the Power6 DFP instructions were not covered by
the assembler tests. I've added a new test file which I believe
covers all the DFP Power6 instructions.
The existing gas/testsuite/gas/ppc/power6.d test is called:
POWER6 tests (includes DFP and Altivec)
And does cover some of the DFP instructions. But, given the number of
additional instructions I'm adding I opted to add a whole new test
file. I've left the original power6.d unchanged, so there is now some
overlap, but I don't think that should hurt much.
