Use a basic multiplicative congruence generator
(https://en.wikipedia.org/wiki/Linear_congruential_generator) to generate a sequence of random buffer accesses within Wasm for the compile time builtins benchmark. This amoritizes the overhead of calling into Wasm while still generating random accesses.My results are:
increment-random-byte-in-buf/concurrency_support=true/compile-time-builtins-host-buf-api time: [9.6652 ns 10.259 ns 10.891 ns]
