Separate VSX code from non-VSX code. For non-VSX code, combine extenddftf2_fprs into extenddftf2 and rename externaldftf2_internal to externaldftf2_fprs. Reorder constraints so that registers come before memory operations. Drop support from converting DFmode to TFmode, if the DFmode value is in a GPR register. (extenddftf2_fprs): Likewise. (extenddftf2_internal): Likewise. (extenddftf2_vsx): Likewise. (extendsftf2): In the expander, only allow registers, but provide insns for the combiner to create for stores and loads.
