  Message : Reduce translator sources compile count to one. With this change, the common sources shared between translator and translator_static are compiled in a static library. There is only one file with exported functions which needs to be compiled for each target. This should reduce ANGLE and chromium build times. BUG=angle:569 Change-Id: I3ce011872323ec988befbd6db731add4fce5787b Reviewed-on: https://chromium-review.googlesource.com/197271 Reviewed-by: Geoff Lang <geofflang@chromium.org> Tested-by: Jamie Madill <jmadill@chromium.org>
