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>

spirv-reader: switch to HLSL-style pipeline IO - When storing to sample_mask output, write to the 0th element - Only make a return struct if it has members - Adjust type signedness coercion when loading special builtins. - Adapt tests - Update expectations for end-to-end tests - Handle sample_mask with stride Input variables normally don't have layout. But they can have it up through SPIR-V 1.4. Handle this case in the SPIR-V reader, by seeing through the intermediate alias type created for the strided array type.

tint: Change all ProgramBuilder literals to 'i' or 'u' suffix Unsuffixed integer literals are currently treated as i32, but will shortly become AbstractInteger. To keep tests behaving identically to how they are currently, change all test literals to using either 'i' or 'u' suffixes.
