bors-servo 57053e03bb Auto merge of #21825 - jdm:backtrace-helpers, r=Manishearth ... Optional backtraces for JS errors and WebGL errors This adds two new build-time features to enable useful debugging tools when investigating why JS and WebGL content isn't working. They're optional because they're quite heavyweight. --- - [x] `./mach build -d` does not report any errors - [x] `./mach test-tidy` does not report any errors - [x] These changes do not require tests because they're optional developer features. <!-- Reviewable:start --> --- This change is [<img src="https://reviewable.io/review_button.svg" height="34" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/servo/servo/21825) <!-- Reviewable:end -->		2018-10-02 06:57:38 -04:00
