  Message : Disable vulkan device select layer for msan build The vulkan device select layer is not built with chrome, so this layer is not built with msan. So loading this layer will cause MemorySanitizer errors. Those errors are false positive. So disable it for msan build. Bug: chromium:1259170 Change-Id: I513d6dd3d4fbc16c62aaa3aa1e7cf299e3e4144a Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3347143 Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Peng Huang <penghuang@chromium.org>
