    Reland "[heap] Add global memory controller" · 880c3202
    Michael Lippautz authored
    Provide a global memory controller used to compute limits for combined
    on-heap and embedder memory. The global controller uses the same
    mechanism (gc speed, mutator speed) and growing factors as the regular
    on-heap controller.
    
    Rely on V8's mechanisms for configured state that stops shrinking the
    limit.
    
    Reland:
    - API fixes with overrides and default versions.
    - Fix of depending on uninitialized values when using the old API.
    - GCTracer: Fixed issue in speed computation.
    - GCTracer: Added unittests.
    
    This reverts commit 5e043f27.
