Vulnerability Type: 
CWE ID: CWE-125
Summary: Insufficient validation of untrusted input in Skia in Google Chrome prior to 59.0.3071.86 for Linux, Windows, and Mac, and 59.0.3071.92 for Android, allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page.
Commit Message: Origins should be represented as url::Origin (not as GURL).

As pointed out in //docs/security/origin-vs-url.md, origins should be
represented as url::Origin (not as GURL).  This CL applies this
guideline to predictor-related code and changes the type of the
following fields from GURL to url::Origin:
- OriginRequestSummary::origin
- PreconnectedRequestStats::origin
- PreconnectRequest::origin

The old code did not depend on any non-origin parts of GURL
(like path and/or query).  Therefore, this CL has no intended
behavior change.
