Cuong Manh Le 4bcf94b023 all: prevent fakePC overflow on 386 in libfuzzer mode
fakePC uses hash.Sum32, which returns an uint32. However, libfuzzer
trace/hook functions declare fakePC argument as int, causing overflow on
386 archs.

Fixing this by changing fakePC argument to uint to prevent the overflow.

Fixes #56141
