This pretenuring was added in https://codereview.chromium.org/5220007, back when it was necessary in order to allow use of the closure as a "constant function" property. This should no longer be the case, and the pretenuring causes some unfortunate downstream effects. This patch removes the parser's setting of this bit. If it doesn't cause regressions on the perf bots, followup CLs will remove the rest of the support for this feature.

This is a follow-up to https://chromium-review.googlesource.com/904662 as I forgot this callsite there. The perf tests still haven't recovered from decreasing the worker count by 1 to account for main thread (crbug.com/809961) and I assume this line is at fault. If this is correct, it also indicates ConcurrentMarking as a great area to focus since a single extra worker appears to be making a significant difference.

Implements the change outlined in https://github.com/tc39/ecma262/pull/890, which has been ratified and pulled into the specification. In particular, template callsite objects are no longer kept in a global, eternal Map, but are instead associated with their callsite, which can be collected. This prevents a memory leak incurred by TaggedTemplate calls. Changes, summarized: - Remove the TemplateMap and TemplateMapShape objects, instead caching template objects in the feedback vector. - Remove the `hash` member of TemplateObjectDescriptor, and the Equals method (used by TemplateMap) - Add a new FeedbackSlotKind (kTemplateObject), which behaves similarly to FeedbackSlotKind::kLiteral, but prevents eval caching. This ensures that a new feedback vector is always created for eval() containing tagged templates, even when the CompilationCache is used. - GetTemplateObject bytecode now takes a feedback index, and only calls into the runtime if the feedback is Smi::kZero (uninitialized).

According to the spec, if an imported function gets exported, the exported function has to be identical to to imported function. With this CL we initialize the list of potential js_wrappers_ with all wasm function we imported. Therefore no new wrappers are generated for these functions.

Currently, the LiftoffCompiler can bail out on unsupported instructions, but the LiftoffAssembler can not. This makes it difficult to iteratively implement the platform specific part of the assembler. With this CL, also the assembler can bail out if an unimplemented assembler method is called. This allows to test already implemented methods.

When collecting stack frame information during a profiler tick event, we apply a filter on the instructions at the current pc to avoid collecting (wrong) stack frames while a frame is being setup/torn down. While this detection makes sense for compiled JavaScript code, it also filters out ticks in the C++ code base of v8. This change only applies the filter if the pc lies within a region that could potentially contain compiled JavaScript code.

Moves generation of speculation poison to be based on the PC target vs the actual PC being executed. The speculation poison is generated in the prologue of the generated code if CompilationInfo::kGenerateSpeculationPoison is set. The result is stored in a known register, which can then be read using the SpeculationPoison machine node. Currently we need to ensure the SpeculationPoison node is scheduled right after the code prologue so that the poison register doesn't get clobbered. This is currently not verified, however it's only use is in RawMachineAssembler where it is manually scheduled early. The Ignition bytecode handlers are updated to use this speculation poison rather than one generated by comparing the target bytecode.

d8's fragile path manipulation code requires that backslashes are replaced with slashes before further processing. NormalizePath() is the function that does this, and it's called in almost all the required cases. But because of Clusterfuzz runs tests with an absolute URL on the commandline, there was one case that slipped through. This patch closes that gap. No test added since this only reproduces under Clusterfuzz, not in running mjsunit tests.

This is a purely cosmetic change. Rename all local variables and parameters of type CallDescriptor* to "call_descriptor". For locals that are now named "call_descriptor", use auto upon initialization, following the Google style guide (https://google.github.io/styleguide/cppguide.html#auto).

Extend the current OOB support for typed arrays to also handle the negative integer indices in the fast-path. This is safe because in ECMAScript we never look up integer indexed properties (including negative indices) on typed arrays in the prototype chain. This reduces the performance cliff shown in the benchmark on the relevant bug from console.timeEnd: Runtime deopt, 596.185000 console.timeEnd: Runtime deopt, 1444.289000 console.timeEnd: Runtime deopt, 1445.191000 console.timeEnd: Runtime deopt, 1443.008000 to console.timeEnd: Runtime deopt, 590.017000 console.timeEnd: Runtime deopt, 784.899000 console.timeEnd: Runtime deopt, 792.428000 console.timeEnd: Runtime deopt, 786.740000 which corresponds to a 2x improvement overall. It's not for free, especially not in this benchmark, but the cliff isn't as bad as it was previously.
