X87: [proxies] fix access issue when having proxies on the prototype-chain of global objects.

  port 2c75e3d2abc3eba3337a09afcd0dfa3e653ff006 (r32903)

  original commit message:
  We can no longer just walk the prototype chain without doing proper access-checks. When installing a proxy as the __proto__ of the global object we might accidentally end up invoking cross-realm code
  without access-checks (see proxies-cross-realm-ecxeption.js).
