all: collect raw coverage
Raw coverage might be important when e.g. analysing the origins of
out-of-place coverage in coverage reports or understanding why the
fuzzer could not reach deeper code.
If "raw_cover" is set to true, syzkaller will remember unsorted and
unduplicated coverage (PCs) for each its corpus program.
