RFR: JDK-8243156 Fix deprecation and unchecked warnings in microbenchmark

[Claes Redestad]

I've looked at the benchmarks that move from explicit constructors to
autoboxing and don't think we'll see any difference in behavior: all
usage during setup, and benchmarks don't seem to accidentally depend on
identity.

LGTM.
