At least macOS 11.3, iMacPro1,1, Radeon Pro Vega 56

Something seems bizarre about these failures. Chrome on top of ANGLE works just fine with these tests: /Applications/Google\ Chrome\ Canary.app/Contents/MacOS/Google\ Chrome\ Canary --user-data-dir=/tmp/c1 --use-cmd-decoder=passthrough Can confirm they're failing with Safari Technology Preview even on 10.15.7 on a 2017 15" MacBook Pro. We eliminated all redundant ANGLE shader compiler instances on the WebKit side and should be configuring ANGLE the same way Chromium does.
