  Message : common: Add aligned memory allocator. This will be useful for the Vulkan pipeline state cache. This cache wants to pack the pipeline description very carefully into a specific number of bits, using the "alignas" keyword. Using this keyword requires an aligned allocator, which we can lift from Chromium's base/memory submodule. Also includes a unittest copied from Chrome. Bug: angleproject:2163 Change-Id: I25976be4610636db3f43552bba23d823f5a49a24 Reviewed-on: https://chromium-review.googlesource.com/837944 Reviewed-by: Corentin Wallez <cwallez@chromium.org> Reviewed-by: Frank Henigman <fjhenigman@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org>
