Add support for non-NEON ARM FFT

This adds non-NEON support for float FFTs and two new functions for
the forward and inverse real float FFTs.  The two new functions will
automatically choose whether to use the NEON or non-NEON versions.

Tests updated to include separate test programs for the non-NEON code.
