    [builtins] Enable embedded builtins and add testing variants · abcc28ce
    jgruber authored
    This enables the v8_enable_embedded_builtins gn flag on non-ia32 builds
    and adds a new --stress-off-heap-code test mode to fyi bots.
    
    v8_enable_embedded_builtins=true changes accesses to constants and
    external references to go through the root list in builtins code.
    
    --stress-off-heap-code copies builtins code off-heap on isolate
    creation.
    
    A few drive-by-fixes:
    - ensure that we actually inspect the correct builtin during
      isolate-independence testing.
    - relax tests to decrease maintenance (now we only fail if a builtin
      should be isolate-independent but isn't).
    - switch to a different off-heap-trampoline register on arm due to
      conflicts with custom stub linkages.
