  Message : Make angle::Result an enum. This moves away from a class type to a value type. This should improve performance when using angle::Result as a return value. Previously the generated code would return a pointer instead of a value. Improves performance in the most targeted microbenchmark by 10%. In more realistic scanarios it will have a smaller improvement. Also simplifies the class implementation and usage. Includes some unrelated code generation changes. Bug: angleproject:2491 Change-Id: Ifcf86870bf1c00a2f73c39ea6e4f05ca705050aa Reviewed-on: https://chromium-review.googlesource.com/c/1356139 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org>
