We always invoke libgccjit in a subprocess, the difference between sync
and async is:
- in sync compilation we run all our compiler *but* libgccjit in process
(libgccjit runs in a subprocess)
- in async all the compilation computation is done in a sub process.
The reason for running libgccjit always in a subprocess is that
unfortunatelly it leaks memory.
