   [VM/Compiler/AOT] Bare instructions 8: Improve AOT code by using pc-relative calls
   
   This CL improves AOT code for StackOverflowInstr/CheckNullInstr:
   
     * On ARM we can do a conditional pc-relative calls for the stack overflow
       checks, getting rid of the slow-paths entirely.
   
     * On ARM64 we can do pc-relative calls on the slow path, avoiding an
       extra load.
   
   Flutter gallery size impact (in bare instructions mode):
     * ARM: -3.7% RX
     * ARM64: -1.4% RX
