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> 2021-05-18 10:28:48 +00:00			`struct S {`

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.
