There's extra logic in the CompileBroker for waiting for blocking JVMCI compilations to try and prevent deadlock (JDK-8148507). However, this is not relevant for libgraal which does not run Java code that can be accessing locks used by other threads.

However, over time, this logic was extended to unblock a blocking compilation when a libgraal internal deadlock is detected. It turns out that this hides deadlocks or long compilations that should be solved in libgraal itself.

This PR makes blocking compilation with libgraal the same as blocking compilations for C1 and C2.

Testing: This has been tested for about 3 months against libgraal.
