target-mips: use the softfloat floatXX_muladd functions
Use the new softfloat floatXX_muladd() functions to implement the madd, msub, nmadd and nmsub instructions. At the same time replace the name of the helpers by the name of the instruction, as the only reason for the previous names was to keep the macros simple.
