Martin Kustermann ca2db2ad53 [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
