Now that it is implicit in function entry and loop iteration, there is no need for an explicit bytecode. Also updated tests that used explicit bytecodes.

Since now the IterationBody StackChecks are implicit within JumpLoops, we are able to eagerly deopt in them. If we do that, whenever we advance to the next bytecode we don't have to advance to the next literal bytecode, but instead "advance" in the sense of doing the JumpLoop. Adding tests that test this advancing for wide and extra wide JumpLoops. Also, marking JumpLoop as needing source positions since now it has the ability of causing an interrupt.

The Factory/OffThreadFactory allows us to cleanly separate object construction behaviour between main-thread and off-thread in a syntactically consistent way (so that methods templated on the factory type can be made to work on both). However, there are cases where we also have to access the Isolate, for handle creation or exception throwing. So far we have been pushing more and more "customization points" into the factories to allow these factory-templated methods to dispatch on this isolate behaviour via these factory methods. Unfortunately, this is an increasing layering violation between Factory and Isolate, particularly around exception handling. Now, we introduce an OffThreadIsolate, analogous to Isolate in the same way as OffThreadFactory is analogous to Factory. All methods which were templated on Factory are now templated on Isolate, and methods which used to take an Isolate, and which were recently changed to take a templated Factory, are changed/reverted to take a templated Isolate. OffThreadFactory gets an isolate() method to match Factory's. Notably, FactoryHandle is changed to "HandleFor", where the template argument can be either of the Isolate type or the Factory type (allowing us to dispatch on both depending on what is available).

Leszek Swirski authored
Add support for internalizing an AstValueFactory using the off-thread factory. Includes adding ConsString support to OffThreadFactory. This introduces a Handle union wrapper, which is used in locations that can store a Handle or an OffThreadHandle. This is used in this patch for the internalized "string" field of AST strings, and will be able to be used for other similar fields in other classes (e.g. the ScopeInfo handle in Scope, object boilerplate descriptor handles, the inferred name handle on FunctionLiterals, etc.). It has a Factory-templated getter which returns the appropriate handle for the factory, and a debug-only tag to make sure the right getter is used at runtime. This union wrapper currently decomposes implicitly to a Handle if the getter is not called, to minimise code changes, but this implicit conversion will likely be removed for clarity.

Since the turbo_decompression_elimination flag is removed, there are several methods in machine-type.h that get simplified, e.g TypeCompressedTaggedPointer() can be replaced by just "TaggedPointer()". Also Removing the creation of Change to/from Compressed nodes. Removing these Change nodes' logic is left to a follow-up CL.

This enables using TNode types without including code-assembler.h, which is useful when generating CallInterfaceDescriptors. As a drive-by, this moves TNode from v8::internal::compiler to v8::internal. It's only used outside of the compiler anyway.

This is a reland of 8b89a7c3 Reland after disabling the test getting deadlocked with '--gc_stress' flag. The CL was reverted because of the 'wasm/grow-shared-memory' test from the mjsunit test suite deadlocked for the 'gc_stress' variant.

The functionality of the GetIterator bytecode introduced previously is now extended from loading the @@iterator property to calling the property as well. This change basically absorbs the functionality of additional two bytecodes - Star, CallProperty0 in the GetIterator bytecode. Importantly, this change handles the cases of eager and lazy deoptimization in the middle of the bytecode, i.e., lazy deopt for LdaNamedProperty and eager deopt of the CallProperty0 bytecode, using the continuation builtins. This mechanism can work as a template for the future bytecode that require handling such inter-bytecode deopt scenario. The tests evaluating the eager and lazy deopt scenarios are also included.

Replace uses of WordEqual on two tagged representation nodes with a new TaggedEqual helper, which on pointer compressed configs only compares the bottom 32-bits of the word. We no longer allow using WordEqual on anything not known to be a WordT (i.e. Node* or TNode<Object>). In the future, this may allow us to ignore the top bits of an uncompressed Smi, and have simpler decompression, though this patch is not sufficient for such a change. As a necessary drive-by, TNodify a bunch of stuff.

This changes Compiler::CollectSourcePositions to skip finalization of the BytecodeArray, constant table, handler table, ScopeInfos as well as internalization of Ast values since only the source position table is used and the others will be collected soon after by the GC. It will also now avoid recompiling inner functions that would otherwise be eagerly compiled. BytecodeArrayWriter::ToBytecodeArray has been changed to never populate the source_position_table.

This is the first in a series of changes to reduce the number of bytecodes generated for the iteration protocol based operations. The GetIterator bytecode introduced in this change currently loads the @@iterator symbol from an object that was previously done using the LdaNamedProperty bytecode. This change uses builtin-based mechanism that would be extended to perform additional operations in the future on absorbing the bytecodes associated with the GetIterator operation from the iteration protocol.

We translate loads with TaggedXXX (XXX in {"", "Signed", "Pointer"}) representation in CSA into loads of CompressedXXX + ChangeCompressedXXXToTaggedXXX in the raw-machine-assembler. This way, CSA doesn't need to know about Compressed values since we are introducing an explicit "decompress" node. Also updating tests that were checking for the load nodes.

We want to allocate feedback vectors lazily in lite mode. To do that, we should create closures with the correct feedback cell. This cl allocates feedback cell arrays to hold these feedback cells in lite mode. This cl also modifies the compile lazy to builtin to expect these arrays in the feedback cell. Drive-by fix: InterpreterEntryTrampoline no longer has argument count in a register. So updated comments and removed unnecessary push/pop of this register.
