38410c082f [CFI] Remove function pointer casts 
Control Flow Integrity [1] indirect call checking verifies that function
pointers only call valid functions with a matching type signature. This
change eliminates function pointer casts that were causing cfi-icall
failures.

e03f0ec319 sharp_yuv: use 14b fixed-point precision for gamma 
Output is <.1% difference in size, randomly.

Speed is 30-50% faster (-m 0 -sharp_yuv).
It also gives the exact same output on ARM and x86, because floats
are no longer used.
