Poor Hardware Rasterization Performance - Haswell GPU

Reported by mailerd...@gmail.com, Aug 17 2017

Issue description

UserAgent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3184.0 Safari/537.36

Example URL:
https://testdrive-archive.azurewebsites.net/performance/chalkboard/

Steps to reproduce the problem:
1. Visit Chalkboard
2. Run the demo
3. Check the performance result

What is the expected behavior?
The test should complete in 10 seconds.

What went wrong?
Without hardware rasterization enabled, the test completes in 10 seconds or so, but with rasterization enabled, the test takes twice as long.

Does it occur on multiple sites: Yes

Is it a problem with a plugin? N/A 

Did this work before? No 

Does this work in other browsers? Yes

Chrome version: 62.0.3184.0  Channel: beta
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: 

Please note that Iris Pro graphics on variants of Haswell CPUs are not the same as HD 4x00 on most Haswell CPUs.

See this bug:

https://bugs.chromium.org/p/chromium/issues/detail?id=751006

Please close this ticket and label it "Wontfix".

Intel GT2 performance is poor, and that's what it comes down to.  Use an Intel GT3 or better for the best Chromium hardware rasterization experience.

Are we missing a blacklist entry here?

From reading the other bug, it sounds like this is a case where the one particular benchmark regresses with hardware raster, but we don't believe this will be the case on most sites. Duping to the other bug.
