Tests for : BasicMaths, ComplexMaths, Stats, FastMath
Filtering, Distances, Support.
Some tests are disabled because only a subset
of the functions has been converted to f64.
Longer test patterns for BasicMaths, ComplexMaths and Statistics.
Corrected saturation bug in MVE code for arm_abs_q7,
arm_cmplx_conj_q15 and arm_cmplx_conj_q31.
Added a new header of vectorial inline functions for Neon and Helium.
This header is used in the implementation of some functions.
Corrected used of float (float functions rather than double ones).
