* config/mips/mips.h (FP_INC, UNITS_PER_FPVALUE): New macros.
* config/mips/mips.c (compute_frame_size): Retrofit them here.
(save_restore_insns, mips_expand_epilogue): And here.
(build_mips16_call_stub): And here.
(mips_function_value): Use the new macros to decide whether a single
or complex float can be returned in floating-point registers. Return
a parallel rtx in the complex case.
