      [ptr-compr, heap] Use system pointer size for heap limit computation · 8732596c
      Ulan Degenbaev authored 
      A pointer-compressed heap has the same heap limit heuristics as a 32-bit
heap. Specifically, the heap limit is restricted to 1GB due to scarce
virtual addresses space on 32-bit platforms. That limitation does not
apply for pointer-compressed heaps which can use 4GB.

This CL changes the heap limit computation to use system the pointer
size instead of the tagged pointer size. Note that the young generation
limit continues to use the tagged pointer size.

      Reland "[heap] Add global memory controller" · dac86be2
      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.

This reverts commit 5e043f27.
