JDK-8355466 - [Umbrella] Add more randomization to the JIT for stress testing
Description
replace Xcomp w/ a solution which doesn't reduce coverage, but make cover situations closer to reallife ones. instead of compiling a method w/o any profiling info, compiler can read info from a file or randomly generate it on-the-fly.
Comments
This item will still be valid for Future JIT which use Profiling. But currently we don't resources to work on it.
