Softfloat mode with register ABI is not implemented yet. In particular, we did not rewrite the float types in AuxCalls to integer types, so arguments are still passed in floating point registers, which do not exist in softfloat mode. To make it work I think we may want to reorder softfloat pass with expand_calls pass. We also need to rewrite the OpArgFloatRegs for the spilling of non-SSA-able arguments, which may involve renumbering interger arguments. Maybe in softfloat mode we want to just define the ABI with 0 float registers. They are not fundamentally hard, but may be not worth doing for the moment, as we don't use softfloat mode on AMD64 anyway. Run the test with noregabiargs. Also in the compiler reject -d=softfloat if regabiargs is enabled.
