Alex Bradbury d760910d3d [RISCV] Add another potential combine to {double,float}-bitmanip-dagcombines.ll 
(fcopysign a, (fneg b)) will be expanded to bitwise operations by
DAGTypeLegalizer::SoftenFloatRes_FCOPYSIGN if the floating point type isn't
legal. Arguably it might be worth doing a combine even if it is legal.

Alex Bradbury 38c4ec31cb [RISCV] Add tests to demonstrate bitcasted fneg/fabs dagcombines 
This target-independent code won't trigger for cases such as RV32FD where
custom SelectionDAG nodes are generated. These new tests demonstrate such
cases. Additionally, float-arith.ll was updated so that fneg.s, fsgnjn.s, and
fabs.s selection patterns are actually exercised.
