Assembler::AbortedCodeGeneration() is defined in assembler-arm64.h, but it calls into Constant::Clear() which is defined in assembler-arm64.cc. This introduces dependency to v8_base component when including assembler-arm64.h which is not always possible like for V8 unittests target. To fix this, we could define both in the same file, like Assembler::IsConstPoolEmpty() calls Constant::Clear() and both are defined in assembler-arm64.h, so it works fine.

BytecodeLabels for forward jumps may create a dead basic block if their corresponding jump was elided (due to it dead code elimination). We can avoid generating such dead basic blocks by skipping the label bind when no corresponding jump has been observed. This works because all jumps except JumpLoop are forward jumps, so we only have to special case one Bind for loop headers to bind unconditionally. Since Binds are now conditional on a jump existing, we can no longer rely on using Bind to get the current offset (e.g. at the beginning of a try block). Instead, we now expose the current offset in the bytecode array writer. Conveniently, this means that we can be a bit smarter about basic blocks around these statements. As a drive-by, remove the unused Bind(target,label) function.

This CL introduces a new contextual 'LanguageSererData'. Its purpose is to hold all the eagerly calculated data needed to answer language server requests. The first thing collected are the definitoins of some IdentifierExpresisons and macro/builtin call-sites. Collecting this data is not necessary for normal compilation, so it is disabled by default and can be enabled via a Torque compiler option. Since the holder class is a contextual for which no scope exists during normal compilation, accidental collection of unnecessary language server data *should* be prevented.

The SourceRangeAstVisitor has custom logic for blocks ending with a statement that has a continuation range. In these cases, the trailing continuation is removed which makes the reported coverage ranges a bit nicer. throw Error('foo') consists of an ExpressionStatement, with a Throw expression stored within the statement. The source range itself is stored with the Throw, not the statement. We now properly extract the correct AST node for trailing throw statements.

This will allow the devtools UI to display private fields on the scope panel. Instead of extending GetInternalProperties, we expose a separate GetPrivateFields method on the debug interface. This allows us to do better type checking, for example, we can directly cast to a v8::Private as this can only contain private fields. This also allows us to have better constraints on the input type -- v8::Object, as opposed to a v8::Value. The KeyAccumulator is extended to collect private names for the PRIVATE_NAMES_ONLY PropertyFilter.

This is a port of the improvements to the ArgumentsAdaptorTrampoline that previously landed for x64. It skips the arguments adaptor frame creation if the callee cannot observe the actual arguments (as indicated by the "is_safe_to_skip_arguments_adaptor" bit on the SharedFunctionInfo), and instead just massages the current stack frame appropriately (either by pushing more undefineds in case of under application, or by removing the superfluous arguments in case of over application).

Constructors have been removed. Initialization syntax with {} for structs and classes is now limited to the initialization expressions for the fields, so "constructors" deviating from that explicit and complete list of field initialization values must be declared as separate macros.
