 swscale self tests fail with assertion since recent changes

 How to reproduce:
 {{{
 make -j32 libswscale/tests/swscale
 libswscale/tests/swscale
 ...
 grayf32be -> grayf32be
  grayf32be 96x96 -> grayf32be  64x 64 flags= 1 CRC=d85005d7 SSD=    0,
 958,  667,    0
  grayf32be 96x96 -> grayf32be  64x 96 flags= 1 CRC=9175737f SSD=    0,
 958,  667,    0
  grayf32be 96x96 -> grayf32be  64x128 flags= 1 CRC=313242fb SSD=    0,
 958,  667,    0
  grayf32be 96x96 -> grayf32be  96x 64 flags= 1 CRC=d4c1d3d3 SSD=    0,
 958,  667,    0
 Assertion c->srcBpc == 16 failed at libswscale/x86/swscale.c:533
 Aborted (core dumped)

 }}}

 This is important as it prevents the normal workflow of testing changes to
 libswscale. Meaning, changes cannot be tested fully currently.
