[9] RFR(L) 8166415: Integrate AOT tool JAOTC

[Paul Sandoz]

Hi Vladimir,

I think we should adjust to depend on the internal Unsafe and update the java.base module to export qualified to jdk.aot (like that for jdk.vm.compiler). It could easily be done later rather than now, if so I can log an issue.

Paul.
