Add new layout test baseline for modified V8 compiler output. The next V8 roll into chromium is pending on this issue.

V8 revision 15503 changed compiler output that requires a new baseline for two blink tests.

See: https://code.google.com/p/v8/source/detail?r=15503

The temporary expectation will be removed after the next V8 roll.
