Fixed threshold(THRESH_TOZERO) at imgproc(IPP)

* Fixed #16085: imgproc(IPP): wrong result from threshold(THRESH_TOZERO)

* 1. Added test cases with float where all bits of mantissa equal 1, min and max float as inputs
2. Used nextafterf instead of cast to hex

* Used float value in test instead of hex and casts

Vincent Rabaud 3da17c42a4 Use NaN-safe clip function. 
This is to prevent more NaN to int conversions like in #21111.

Alexander Alekhin 52c423a423 build: winpack_dldt with dldt 2021.4.2 2021-12-14 09:00:43 +00:00
Vincent Rabaud 542b3e8a64 Fix harmless signed integer overflow. 
When computing:
t1 = (bayer[1] + bayer[bayer_step] + bayer[bayer_step+2] + bayer[bayer_step*2+1])*G2Y;
there is a T (unsigned short or char) multiplied by an int which can overflow.
Then again, it is stored to t1 which is unsigned so the overflow disappears.
Keeping all unsigned is safer.

Vincent Rabaud 6b4ea68bc7 Solve Rect overflow issues. 
Fow now, it is possible to define valid rectangle for which some
functions overflow (e.g. br(), ares() ...).
This patch fixes the intersection operator so that it works with
any rectangle.
