/*****************************************************************************
PhaseHalfPi2F64Sse2.h
Author: Laurent de Soras, 2020
From the input signal, generates two signals with a pi/2 phase shift, using
SSE instruction set. Works on vectors of 2 double.
This object must be aligned on a 16-byte boundary!
Template parameters:
- NC: number of coefficients, > 0
