    runtime: don't hard-code physical page size · 6dda7b2f
    Austin Clements authored
    Now that the runtime fetches the true physical page size from the OS,
    make the physical page size used by heap growth a variable instead of
    a constant. This isn't used in any performance-critical paths, so it
    shouldn't be an issue.
    
    sys.PhysPageSize is also renamed to sys.DefaultPhysPageSize to make it
    clear that it's not necessarily the true page size. There are no uses
    of this constant any more, but we'll keep it around for now.
    
    Updates #12480 and #10180.
