  testsuite: keep exit code 134 for -fcheck-prim-bounds tests on the JS backend
  
  The improved -fcheck-prim-bounds error messages and EXIT_FAILURE (1) exit
  status are native-only; the JS backend still aborts via h$exitProcess(134).
  Expect 134 on the JS arch for the bulk tests, and skip the message-pinning
  tests T26964/T26964b there, since the JS backend emits no message.
