Relax builtin precision tests, fix issue in div rounding
* sin(), cos() and derived: Use |x| * 2^-10 for mediump inputs outside
of range [-pi,pi].
* asin(), acos(), and atan(): Use 4096 ULP for highp (from OpenCL's
fast relaxed math).
* modf(): allow any value, including NaN, as fractional if Inf support
is not mandated for the precision (lowp and mediump).
* atan(y, x): allow any value if y or x is Inf and no Inf support is
mandated for the precision.
* div (and derived): allow rounding of -/+inf to -/+maxval when both
inputs are ordinary and denominator is not 0 (legal in RTZ mode).
