Similar to MRootList tracing, trace WarpSnapshot GC pointers in IonCompileTask::trace.
Note that this is only for off-thread compilations. Main thread compilation can't
trigger GC while the snapshot is live.

This simplifies the next patch but also lets us use pattern matching with lambdas.

This adds a wrapper type that asserts pointers are tenured. TraceWarpGCPtr now
requires the new type.
