This is a reland of commit e2066ff6 Changes since revert: - Rebased against c9918524, which uses the external pointer table for the WaiterQueueNode stored in the state field when compressing pointers. This relaxes the alignment requirement of the state field to be 4-bytes when compressing pointers. - Moved the state field into the JSSynchronizationPrimitive base class, since alignment and padding can now be made simpler.

This might or might not give clang-tidy a hint that the reported case (see issue) cannot happen. It might also generate slightly better code by giving hints to the compiler. Note that V8_ASSUME is actually a DCHECK in DEBUG builds, so we do not loose any checks here. Some DCHECKs were removed because they are redundant (RegisterBase::code() assumes to be only called on valid registers).

Add a --deopt-to-baseline flag, on by default, which allows returning to sparkplug code when deoptimizing. However when we turn this off, no longer deoptimizing to baseline code means we can omit marking most bytecodes as valid jump targets. Leaving just OSR and exception handling entry points. This reduces the baseline code size by ~18% on Arm64.

... - a code range size agnostic version of InterpreterEntryTrampoline builtin. The new builtin is fully compatible with the default version and used as a template for creating interpreter entry trampoline Code objects when --interpreted-frames-native-stack is enabled. This CL introduces a new assembler option "position_independent_code" which affects the way builtin calls are generated. This mode is enabled only for InterpreterEntryTrampolineForProfiling. Motivation: * InterpreterEntryTrampoline uses RelocInfo::CODE_TARGET for calling other builtins which requires the code range to be small enough to allow PC-relative jumps/calls between Code objects. This is the reason why --interpreted-frames-native-stack was not supported on arm and might not work on arm64 because the code range is bigger than the max PC-relative distance for call/jump instructions. The new builtin calls other builtins via builtins entry table which makes the code fully relocatable and usable for any code range size. * RelocInfo::CODE_TARGET requires a target code to be materialized as a Code object which contradicts the Code-less builtins goal. * The --interpreted-frames-native-stack is rarely used in the wild but we have to pay the price of deserializing InterpreterEntryTrampoline builtin as a Code object which consumes address space in the code range and thus limits the number of V8 isolates that can be created because of code range exhaustion. Now the pointer compression cage becomes the limiting factor instead of the code range. * We can remove complicated logic of Factory::CopyCode() and respective support on GC side.

Many messages already do not end in a ".", which makes sense for embedders that format location and message in one line, like Chrome. Before: V8 error: Empty MaybeLocal. (v8::ToLocalChecked). After: V8 error: Empty MaybeLocal (v8::ToLocalChecked).

In release builds, FLAG_debug_code is statically false. Without LTO, this information is not available to callers of the various Assert functions though. This CL defines the methods as empty if V8_ENABLE_DEBUG_CODE is not set. This removes some calls from non-LTO builds, and might even slightly improve LTO builds if we enable more optimizations earlier in the pipeline.

JSTypedArray needs the base_pointer ByteArray immediately if it's on heap. JSTypedArray's base_pointer was initialized to Smi::uninitialized_deserialization_value at first when deserializing, and if base_pointer was deferred, we will mistakenly check JSTypedArray not on heap.
