Patches #5..8 just add comments and reformat movd{f,d} constraints and
attributes so that it is a lot easier to tell which constraints and attributes
go together.  These do not (or at least should not) change the code generated.
Patch #9 does the same thing for mov{sf,sd} when floating point registers are
not available.

I have done both big and little endian bootstrap builds with all 5 patches
installed.  There were no regressions.

	* config/rs6000/rs6000.md (mov<mode>_softfloat64, FMOVE64):
	Reformat alternatives and attributes so it is easier to identify
	which constraints/attributes go with which instruction.
