rs6000: Separate shrink-wrapping for FPRs
This patch implements separate shrink-wrapping for the non-volatile floating point registers (FPR14..FPR31). It is pretty much exactly analogous to the code for GPRs. * config/rs6000/rs6000.c (struct machine_function): Add field fpr_is_wrapped_separately. (rs6000_get_separate_components): Use 64 components. Handle the new FPR components. (rs6000_components_for_bb): Handle the FPR components. (rs6000_emit_prologue_components): Handle the FPR components. (rs6000_emit_epilogue_components): Handle the FPR components. (rs6000_set_handled_components): Handle the FPR components. (rs6000_emit_prologue): Don't output prologue code for those FPRs that are already separately shrink-wrapped. (rs6000_emit_epilogue): Don't output epilogue code for those FPRs that are already separately shrink-wrapped. From-SVN: r248256
