WGSL: RewriteMultielementSwizzle WGSL doesn't support assignments to multi-element swizzles. This is used in a lot of shader tests, so temporarily work around this with an AST traverser that splits these assignments into multiple assignments that only assign to single element swizzles. One special case is multiplication-by-a-matrix assignment: vec.xy *= mat; is converted to vec.x = (vec.xy * mat).x; vec.y = (vec.xy * mat).y; Bug: angleproject:392542001 Change-Id: I3f393039aae13eb3f2c5dc5e553f68eb03b6316d Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/6847280 Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Commit-Queue: Matthew Denton <mpdenton@chromium.org> Reviewed-by: Liza Burakova <liza@chromium.org>
