Update src/tint unittests to new @stage format. This CL updates all of the Tint unittests to the new @stage shorter syntax. This also updates the WGSL writer to emit the new short forms instead of using the deprecated form.

Implement Pointers and References This change implements pointers and references as described by the WGSL specification change in https://github.com/gpuweb/gpuweb/pull/1569. reader/spirv: * Now emits address-of `&expr` and indirection `*expr` operators as needed. * As an identifier may now resolve to a pointer or reference type depending on whether the declaration is a `var`, `let` or parameter, `Function::identifier_values_` has been changed from an ID set to an ID -> Type* map. resolver: * Now correctly resolves all expressions to either a value type, reference type or pointer type. * Validates pointer / reference rules on assignment, `var` and `let` construction, and usage. * Handles the address-of and indirection operators. * No longer does any implicit loads of pointer types. * Storage class validation is still TODO (crbug.com/tint/809) writer/spirv: * Correctly handles variables and expressions of pointer and reference types, emitting OpLoads where necessary. test: * Lots of new test cases Fixed: tint:727 Change-Id: I77d3281590e35e5a3122f5b74cdeb71a6fe51f74 Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/50740 Commit-Queue: Ben Clayton <bclayton@chromium.org> Kokoro: Kokoro <noreply+kokoro@google.com> Reviewed-by: David Neto <dneto@google.com>
