target/ppc: Move dcmp{u,o}[q],dts{tex,tsf,tsfi}[q] to decodetree 

Move the following instructions to decodetree:
dcmpu:    DFP Compare Unordered
dcmpuq:   DFP Compare Unordered Quad
dcmpo:    DFP Compare Ordered
dcmpoq:   DFP Compare Ordered Quad
dtstex:   DFP Test Exponent
dtstexq:  DFP Test Exponent Quad
dtstsf:   DFP Test Significance
dtstsfq:  DFP Test Significance Quad
dtstsfi:  DFP Test Significance Immediate
dtstsfiq: DFP Test Significance Immediate Quad
