Add a sanitizing transform to collect input parameters into a struct. HLSL does not allow non-struct entry-point parameters, so any location- or builtin-decorated inputs have to be provided via a struct instead. Bug: tint:511 Change-Id: I3784bcad3bfda757ebcf0efc98c499cfce639b5e Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/44420 Commit-Queue: James Price <jrprice@google.com> Auto-Submit: James Price <jrprice@google.com> Reviewed-by: Ben Clayton <bclayton@google.com>
