This is a reland of fbfa9bf4 The arm64 was missing proper codegen for CFI, thus sizes were off.

While the overall goal of this commit is to change deoptimization entries into builtins, there are multiple related things happening: - Deoptimization entries, formerly stubs (i.e. Code objects generated at runtime, guaranteed to be immovable), have been converted into builtins. The major restriction is that we now need to preserve the kRootRegister, which was formerly used on most architectures to pass the deoptimization id. The solution differs based on platform. - Renamed DEOPT_ENTRIES_OR_FOR_TESTING code kind to FOR_TESTING. - Removed heap/ support for immovable Code generation. - Removed the DeserializerData class (no longer needed). - arm64: to preserve 4-byte deopt exits, introduced a new optimization in which the final jump to the deoptimization entry is generated once per Code object, and deopt exits can continue to emit a near-call. - arm,ia32,x64: change to fixed-size deopt exits. This reduces exit sizes by 4/8, 5, and 5 bytes, respectively. On arm the deopt exit size is reduced from 12 (or 16) bytes to 8 bytes by using the same strategy as on arm64 (recalc deopt id from return address).

CodeAssembler::Parameter now takes a Type template parameter and performs a checked cast to it. There is also UncheckedParameter which returns a TNode but doesn't check the cast. The original Parameter method is still there as UntypedParameter. Parameter<T>(x) in many cases replaces CAST(Parameter(x)), where the cast is performed inside Parameter. Since Parameter is not a macro, this means it cannot see the original expression or its file name and line number. So the error messages are vaguely useful, Parameter<T>() takes a SourceLocation parameter which with a default value of SourceLocation::Current(), which at least gives us the file name and line number for the error message.

CodeKind::OPTIMIZED_CODE -> TURBOFAN Kinds are now more fine-grained and distinguish between TF, TP, NCI. CodeKind::STUB -> DEOPT_ENTRIES_OR_FOR_TESTING Code stubs (like builtins, but generated at runtime) were removed from the codebase years ago, this is the last remnant. This kind is used only for deopt entries (which should be converted into builtins) and for tests.

With the new Turbofan variants (NCI and Turboprop), we need a way to distinguish between them both during and after compilation. We initially introduced CompilationTarget to track the variant during compilation, but decided to reuse the code kind as the canonical spot to store this information instead. Why? Because it is an established mechanism, already available in most of the necessary spots (inside the pipeline, on Code objects, in profiling traces). This CL removes CompilationTarget and adds a new NATIVE_CONTEXT_INDEPENDENT kind, plus helper functions to determine various things about a given code kind (e.g.: does this code kind deopt?). As a (very large) drive-by, refactor both Code::Kind and AbstractCode::Kind into a new CodeKind enum class.

The cctests were wrong, since they access the first parameter using `Parameter(0)`. They should instead use `Parameter(1)`, since the index 0 is the receiver, and the receiver is set to be always the undefined object in `FunctionTester::Call`. The reason it used to work is that the tests would set up an access to the stack with the wrong number of parameters, accessing only a stack suffix.

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.

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 replaces all typedefs that define types and not functions by the equivalent "using" declaration. This was done mostly automatically using this command: ag -l '\btypedef\b' src test | xargs -L1 \ perl -i -p0e 's/typedef ([^*;{}]+) (\w+);/using \2 = \1;/sg' Patchset 2 then adds some manual changes for typedefs for pointer types, where the regular expression did not match.

This CL applies the equivalent of the Object -> ObjectPtr transformation to MaybeObject and HeapObjectReference. We need no renaming in this case because we can just migrate them both in one go.

There are only very few custom compiled IC handlers left that go in there, and for each compiled handler we only have 1 cache hit on top25; maximally saving 60ms over 33s. Additionally we'll migrate the remaining handlers to data-driven handlers anyway. Let's try to remove this code.

The new AccessorAssembler encapsulates all the functionality that's specific to building LoadIC/StoreIC stubs. There are two header files (accessor-assembler.h and accessor-assembler-impl.h) so that clients of the assembler can include the one, and subclassing assemblers can include the other.
