Log: Changed fuzzer to randomly remove half of the arguments when running
on functions that takes five or more arguments. Original version runs
for a long time when there is 5 arguments in a runtime function (45+
seconds). The fuzzer can be run with all arguments on all functions
regardless of the number of arguments by setting
RUN_WITH_ALL_ARGUMENT_ENTRIES to true in fuzz-natives.js
