The function is quite big and trigonometric functions should not really
be used in speed critical code

Recently normalization (av_normalize_sf) of output was added to av_add_sf.
This normalization is used for better precision for small values and the
purpose of this (quite simple) test case is to test difference between double
and softfloat.
The values used are tailored to maximally highlighte problem with precison when
normalization is not used.

The softfloat functionality is unused, not installed and incomplete.
On platforms without floating point units, the compiler provides a softfloat
implementation so there is no point in carrying this code around locally.
