The Operand class is small enough to be efficiently passed by value. This saves binary size and performance because the Operand does not need to be emitted to the caller's frame and loaded in the callee. Binary saving is 30kB in release mode on x64.

Adding the StringSubstring simplified operator is a precursor to improve inlining of String.p.{substr,substring,slice}. This also contains a drive-by renaming to normalize different spellings of 'Substring'.

The deoptimizer can create argument adaptor frames, in which case we write a return address onto the stack that jumps into the middle of the ArgumentsAdaptorTrampoline builtin. Now that this builtin is off-heap, we need to calculate the return address based on the off-heap instruction stream, not the on-heap trampoline.

Off-heap-safety slightly differs from isolate-independence in that it allows external references and checks instruction-size constraints. This adds the new predicate as well as a cctest verifying it. New DCHECKs are introduced to document assumptions and upcoming work. Note that this breaks the --stress-off-heap-code flag. Fixes will follow in upcoming CLs.

Regular construct stubs eventually call InvokeFunction, which does performs debug hook checking. For builtins such as Object, Array, etc. this approach does not work since they have specialized construct stubs that do not check for the debug hook.

Instead of limiting the number of used spill slots and bailing out if the limit is exceeded, we now store the number of spill slots used and patch the stack frame size after generating all code. This removes a lot of checks and bailouts. Drive-by: Fix a bug with spilling f64 caller frame slots which was uncovered by the additional test coverage after this CL.

Moves the decision whether to embed the constant or perform a lookup through the builtins constants table to CodeAssembler::UntypedHeapConstant. Root constants continue to be embedded (and are later turned into loads through root-register by the backend); non-root constants are added to the constants table at generation-time and loaded from there at runtime. This allows us to remove the recently added boilerplate around CallStub and CallRuntime in a follow-up.

When calling a function through a function table, check whether the instance of the called function differs from the current instance, and in that case call the other function via a c-wasm-entry instead of interpreting it. The c-wasm-entry needs to pass the wasm context, so this CL changes this to receive the wasm context as parameter instead of embedding the context of the calling instance.
