Log message:

	* libm/common/s_ilogb.c:  Adjust documentation to reflect new returns
	(see next items) and that ilogb() and ilogbf() are C99/POSIX.
	* libm/common/s_ilogb.c (ilogb):  Use C99/POSIX FP_ILOGB0 and
	FP_ILOGBNAN returns for 0 and NAN arguments, respectively, instead of
	the prior -INT_MAX and INT_MAX.  The FP_ILOGBx defines in math.h
	presently match the prior hard-codes, so no functional change is
	actually introduced.  (Not at this time, nor planned, but the values
	are permitted to be different, so subsequent edits of math.h could
	possibly cause a functional change.)
	* libm/common/sf_ilogb.c (ilogbf):  Ditto.
