This is a reland of d14ed12e with fix for test failures in lite mode. When handling load named properties (without feedback vectors) we used to miss to runtimes if the prototypes aren't set. This was because we wanted to give the prototype a chance to become fast, since most prototypes start in slow mode but move to fast after the initial setup. Though this check is not really useful when we don't have feedback vectors, and once feedback vectors are allocated we will turn the prototypes fast anyway.

The TraceObject passed to AppendTraceEvent can be completely uninitialized (set to all 0s) in some situations where a flush happens between creation and initialization of the TraceObject. Fix the MockTraceWriter in test-tracing to expect nullptr strings for the name of the object so that it does not try to construct an std::string from a null char*.

Torque semantic analysis is now a four-stage process: 1. The TypeDeclarationVisitor introduces a TypeAlias for every TypeDeclaration* (or derived) in the Torque source, but does not process the TypeDeclaration* itself. 2. All aliases are resolved in a dependency respecting manner. This CL also changes struct member resolution to happen at this point already. Types for classes are created, but their members are not resolved to allow classes to mutually reference each other in their field types. 3. 'value' declarations (macros, etc.) are processed. 4. Members of classes are processed.

To obtain SourcePositions for unary and binary operators, this CL changes the "OneOf" parser rule to produce an Identifier*. Forwarding this new identifier as callee for a CallExpression enables "goto Definition" support for operators in the Language Server. Side note: VSCode won't highlight operators with an underlined font when hovering with Ctrl pressed. "goto Definition" will work nonetheless using default F12 or Ctrl-Click.

Error messages are unspecified in JavaScript and occasional small differences in the compared configurations lead to an unjustified maintenance burden of correctness-fuzzing issues. This CL replaces most error messages with a fixed suppression message during correctness fuzzing (behind a flag). The flag covering all extra behavior for correctness fuzzing is now renamed to --correctness-fuzzer-suppressions.

Until this CL, the Memory benchmark was the only one to be based on a cctest runner; all others use d8. Besides being a tedious exception to the rule, this caused issues such as described in the linked bug (summary: refbuilds are built with v8_static_library, and neither cctests nor unittests support this configuration). Here, we move the Memory benchmark into a d8 runner.

This CL improves SourcePosition support inside the Torque compiler. It starts with the parser, where the SourcePosition of the MatchedInput now encompasses all tokens, not just the first one. Second, AST nodes can now be created with an explicit source position. This can be used to forward the "all encompassing" source position via MatchedInput -> ParseResultIterator to AST nodes. Third, declarables are extended to hold two different SourcePositions: - One represents the whole declarable. For a macro this would inlcude the body as well as the signature. - The other is the SourcePosition of the identifying part of a declarable. In most cases this is the name. For the rest this will stay invalid.
