    Allow resizing the stack for the graph allocator.
    
    The graph allocator now dynamically resizes the number of stack
    slots when running into the limit.
    
    This fixes #8657.
    
    Also loop membership of basic blocks is now available
    in the register allocator for cost heuristics.
    
    (cherry picked from commit 03b7abc19c8b0ec5c606cc2da208d2d004807fe9)
