[snapshot] Use ThinStrings instead of custom forwarding using the hashfield to deserialize internalized strings This is necessary to be able to store the string length next to the hash field in the same 64bit word on 64bit architectures. Otherwise the forwarding pointer will overwrite the length breaking heap guarantees. ThinStrings already just do the right thing, so just use that instead.

With this CL, {CreateDefaultPlatform} returns a unique_ptr to indicate that the caller owns the returned memory. We had several memory leaks where the memory of the DefaultPlatform did not get deallocated. In addition, the {TracingController} of the {DefaultPlatform} also gets received as a unique_ptr. Thereby we document that the {DefaultPlatform} takes ownership of the {TracingController}. Note that the memory of the {TracingController} was already owned by the {DefaultPlatform}, but it was not documented in the interface, and it was used incorrectly in tests. This CL fixes the asan issues in https://chromium-review.googlesource.com/c/v8/v8/+/753583 ([platform] Implement TaskRunners in the DefaultPlatform) R=rmcilroy@chromium.org Cq-Include-Trybots: master.tryserver.chromium.linux:linux_chromium_rel_ng Change-Id: I0d1a6d3b22bb8289dc050b1977e4f58381cec675 Reviewed-on: https://chromium-review.googlesource.com/755033Reviewed-by:Adam Klein <adamk@chromium.org> Reviewed-by:

- Remove weak-collection.js - Adds TFJ builtins for WeakSet and WeakMap constructors - Unified helpers and constructor behavior into a BaseCollectionsAssembler - Fast paths for... - unmodified constructor function - argument is a fast JS array - entries are fast JS arrays, for Map/WeakMap - no arguments passed Quick benchmarks shows significant improvements (1.12x - 5.7x!) for ALL collection constructors (weak and non-weak): https://github.com/peterwmwong/v8-perf/blob/master/weakcollection-constructor/README.md More could be done for performance.

Since each Array literal containing a spread is individually queued for rewriting, there's no need for an AstVisitor here: a simple linear pass through the queue is sufficient. This patch deletes AstExpressionRewriter and all the machinery supporting it in the AST. This code was built with the idea of using it as a general expression rewriting mechanism in the parser, but those use cases never materialized, and Array spread remains the only thing that used this code.

If there is a WeakMap in a retaining path of an object, then we have two choices: 1) use the WeakMap backing store as the retainer. 2) use the key in the WeakMap as the retainer. Both cases can be useful for debugging memory leaks. This patch adds a second parameter to %DebugTrackRetainingPath(). If this parameter is "track-ephemeral-path", then the retaining path printer will use the key in the WeakMap as a retainer. Otherwise, the WeakMap backing store will be reported as the retainer.
