Message : Fix -Wshadow. This still disables the warning for glmark2 instead of fixing it, to avoid needing to upstream a patch. Bug: chromium:794619 Change-Id: Ice602996041d6090c9b09ee81c8ed095c4fa6b2e Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3179860 Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org>
