    [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.
