int is big enough to fully represent exponents of all supported fp
formats.  which even for 80-bit & 128-bit long doubles is only 15
bits.  therefore, scalbln, scalblnf, scalblnl are essentially the
same as scalbn, scalbnf, scalbnl with bounds checking so that
LONG_MIN..INT_MIN, and INT_MAX..LONG_MAX ranges properly raise
exceptions & yield correct values.  looks good to millert@
