All that remains in the wgsl parser that references sem::Type* are the register_constructed funcs/types, and adding an ast::ExternalTexture type. Also: * Added specialization of OperatorArrow for type::TypePairs that returns the value by reference so that operator-> can chain properly. * In a few places where we expect the type to implicitly cast to a pointer for a bool expression, e.g. `if (type)` or `TINT_ASSERT(type)`, I added access to the `.sem` member of the TypePair. I tried adding an implicit cast to bool, but this results in ambiguity in gtest for equality comparisons. * Constified more type pointers in type nodes * Replaced header includes with forward declares in wgsl/parser_impl.h Bug: tint:724 Change-Id: Ie0875aa4d4a5e830e3466ac40c63cd185f357200 Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/48881 Kokoro: Kokoro <noreply+kokoro@google.com> Reviewed-by: Ben Clayton <bclayton@google.com> Commit-Queue: Antonio Maiorano <amaiorano@google.com>
