commit 2a4ea729584ef7faa36d2f64db26b09bd14122ef
Author: stkhapugin <stkhapugin@chromium.org>

[ARC] Converts parts of ios/web/web_state to ARC.

Notable changes:
 * CRWWebViewProxyImpl now uses synthesized getter and ivar for
property contentView
 * CRWJSPOSTRequestLoader now does not create a retain cycle of
CRWWKScriptMessageRouter objects. The cycle seems to have been harmless,
but it definitely brings no value, and it's better to not have it.
