Modified gyp/gn files to support MIPS targets. Implemented thread_info, cpu_context, signal context classes for MIPS target. Addressed MIPS specific signal ordering. Added "MIPS Technologies, Inc." to AUTHORS file. Bug: crashpad:232 Change-Id: Ibfc221ba54088e95f984b9dc6be5fd52f86abcc2 Reviewed-on: https://chromium-review.googlesource.com/1064594 Commit-Queue: Joshua Peraza <jperaza@chromium.org> Reviewed-by: Joshua Peraza <jperaza@chromium.org>
