x86_64: Call finite scalar versions in vectorized log, pow, exp (bz #20033).
Vector math functions require -ffast-math which sets -ffinite-math-only, so it is needed to call finite scalar versions (which are called from vector functions in some cases). Since finite version of pow() returns qNaN instead of 1.0 for several inputs, those inputs are excluded for tests of vector math functions.
