when LLVM_BUILT_WITH_OOP_JIT is on, the tests need to be run two times. First in-process and second time out-of-process. It does make easy for the users to run tests explicitly by just passing a flag.

There is no reason for the user to need to run the tests manually with this flag. You can make the cmake execute two commands (once with the flag and once without), when LLVM_BUILT_WITH_OOP_JIT is on. @vgvassilev What is your opinion on this?

I thought we resolved the static compilation flag already. It should be a runtime flag that we pass to the interpreter and in this way we can make this a test thing.
