Organize AST transforms per backend Most of the AST transforms are written as a workaround to an issue that affects a single backend. This change identifies such transforms and organizes them by backend. They are then only built if the respective backend is. Additionally, about half of the GL transforms are due to mac workarounds, including the large RewriteRowMajorMatrices transform. Mac-specific workarounds are additionally only built on said platform. This change reduces the ANGLE binary size: - 106KB in a Vulkan-only build on Linux - 27KB in a GL-only build on Android (60KB on Linux) Bug: chromium:1084580 Bug: chromium:1161513 Change-Id: I64b334332c0d4f848756c6538af0d8d96864c7e9 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2601346 Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Tim Van Patten <timvp@google.com>
