2898bc522d avcodec/h264idct_template: fix multiple runtime error: signed integer overflow 
Fixes: 857/clusterfuzz-testcase-5319093760557056

Benchmark changes from 335->333 (so if its not a random fluctuation then it would be faster)

45198477de avcodec/simple_idct_template: Fix several integer overflows 
Benchmarks with START_TIMER indicate that the code is faster with unsigned, (that is
with the patch), there was quite some fluctuation in the numbers so this may be just
random
