This includes neon implementation for blend32_16_row for aarch32 and aarch64. I
am seeing one apk to use this code path: 0xbenchmark 2D drawrect and drawarc
test and see improvement of BM score.

Thanks.

Hi, Reviewers, I have one question. Do I need to do anything to see trybot
result or this test will be triggered automatically?

Thanks.

I add trybot by myself, but I don't know what's the meaning of
exception, here. Can someone let me know what I am missing?

Thanks.

The bots_named_like_this are Chromium trybots that don't know how to run for
Skia patches.  I'm not sure what's up with the majority of the purple bots. 
I'll try triggering a few likely candidates for you.

Moving to https://codereview.chromium.org/847363002/ 

I make new one on the top of Reed change.

Thanks.
