Various TurboFan operators and builtins currently conflate the concept of a Unicode code point with that of its UTF-32 and UTF-16 encoding. UTF-16 is only used as an internal optimization, and should not be exposed. This CL separates affected operators and clarifies the naming of various internals. Prior to this CL, StringCodePointAt operator's typing rule was unsound, since it was not strictly limited to returning values in the range of Unicode code points.

This CL deduplicates entries in constant pools based on handle location. This works well because we already use CanonicalHandleScope in the right places. The CL gives a ~2% speed-up on octane for arm64. The code size is reduced significantly as well: Before the change all generated code spend on constant pools during an Octane run on arm64 was 723kb (90398 64bit words) before this change, and after this change only spend 189kb (23615 64bit words) were spend on constant pools. This is a 73.8% reduction.

Rework the implementation of non-external Torque classes to use Struct machinery rather than FixedArray machinery. This allows Torque-only defined 'internal' classes to the automatically generate class verifiers and printers. As part of this change, generate C++ boilerplate accessors for internal Torque classes, since this is a pre-requisite for the verifiers, printers and other Struct-based functionality. Moreover, augment the header-generating functionality in Torque to create separate header files for field offset definitions, internal class C++ definitions and instance types.

Adds basic support for CompressedHeapConstants to Arm64 by moving to a ldr_w instruction and passing COMPRESSED_EMBEDDED_OBJECT as the RelocInfo. However, we still haven't made the COMPRESSED_EMBEDDED_OBJECT be actually compressed in the code-stream (they still take up a full 64-bits). Support for this will be added next. Adding a test on macro assembler that checks that the RelocInfo::COMPRESSED_EMBEDDED_OBJECT is flowing through.

Include directives from outside the src/regexp directory are limited to regexp.h, regexp-stack.h, and regexp-utils.h. We also expose all result codes that can be returned by irregexp code (including RETRY) on the public header since they are needed elsewhere, e.g. in builtins.

This changes Generate_ContinueToBuiltinHelper to generate code to load the builtin address directly from the builtins table rather than going via the executable code in the trampoline's code object. The set up for Generate_ContinueToBuiltinHelper is changed so that the builtin index is stored on the stack in place of the builtin Code object which is no longer needed.
