Share the checkasm_check_pixel macro from hevc_pel in checkasm.h, to allow other tests to use the same. (To use it in other tests, those tests need to have a similar setup for high bitdepth pixels, with a local variable named "bit_depth".) This simplifies the code for checking the output, and can print the failing output (including a map of matching/mismatching elements) if checkasm is run with the -v/--verbose option.
