This makes sure that allocations of {HeapNumber} objects happening in
the JS-to-Wasm and Wasm-to-JS wrappers are ordered with respect to
changes of the {trap_handler::IsThreadInWasm} predicate. Otherwise the
compiler can (and will) move the allocations across changes of this
predicate and cause safety checks to fire.

On arm64, we had {RegisterBase::bit} (defined in assembler.h) and
{CPURegister::bit} (defined in assembler-arm.h). {CPURegister} inherits
from {RegisterBase}. The two methods methods have different
behaviour on the special {no_reg}, which is only relied on in very few
places.
This CL fixes these places to avoid the use of {no_reg}, and removes
the overwritten method.

generate the error message "x is not iterable" instead of the unwieldy
"Cannot read property 'Symbol(Symbol.iterator)' of undefined". However
Runtime::GetObjectProperty, which is used as slow path by LoadICs, did
not check for this case, leading to different messages being generated

Original Commit Message:
With the exception of the InterpreterEntryTrampoline, all builtins are
now isolate-independent and can be embedded into the binary.
This CL updates the corresponding list and also contains a few smallish
tweaks to support having these builtins off the heap:
* wasm: copy the off-heap builtin, not its trampoline.
* Code::contains: support off-heap builtins.
* JSFunction::is_compiled: compare builtin index instead of identity
(this is relevant during mksnapshot when we transition from the
on-heap builtin to its off-heap representation + the trampoline).
* Remove old DCHECKs.
* A few tweaks in macro-assembler ports that have snuck in recently.

Original Commit Message:
Original CL: https://crrev.com/c/1018468
During code generation, we generate self-references (i.e. references to
the Code object currently being generated) as references to a temporary
handle. When the final Code object has been allocated, the handle's
location is fixed up and RelocInfo iteration fixes up all references
embedded in the generated code.
This adds support for this mechanism to the builtins constants table
builder. CodeObject() is now a new handle pointing to a dedicated
self-reference marker in order to distinguish between self-references
and references to undefined. In Factory::NewCode, we patch up
the constants table.

There are likely cleanups that can be done after this CL:
- context-related functions in the interpreter and compiler take ScopeInfo as
well as ScopeType and slot-count as input. The latter 2 should be directly
derived from the former. We should be able to drop FunctionContextParameters.
- ContextExtension is probably not needed anymore, since we now always have the
correct scope_info directly in the SCOPE_INFO_INDEX slot.

This is a preparatory step for implementing generics. Along the way, clean up
and encapsulate a bunch of code, including:
* Fully encapsulate Scope by adding the new class ScopeChain that provide an
abstraction for creating and activating scopes.
* Untangle Modules and Scopes.
* Unify scope activation so that it is always associated with an AST node
and triggered by a RAII helper class.
* Unify (somewhat) how builtins and macros are created, fixing a few
inconsistencies with when and how parameters and their types are declared.
* Create a new Declarations class that brokers between the visitor classes and
the ScopeChain. This moves handling of declaration-related errors out of the
visitors but also makes it possible to do so without polluting Scope and
ScopeChain with details about resolving SourcePositions in error cases.

This CL changes how TypedArray.p.sort is implemented in Torque, mainly
to address the binary memory size of the builtin.
With this CL the memory comes down from 53611 to 4215 (as reported
by --print-builtin-size on a x64.release build).
With the following performance impact
on the relevant benchmarks:
Benchmark Original (JS) Torque (initial) This CL
IntTypes 83.9 263.7 202.3
BigIntTypes 32.1 54.6 47.2
FloatTypes 99.3 138.7 109.3
This is achieved by pushing the Load/Store dispatch based on
the elements kind into separate builtins that are executed
for each load/store. This results in only one version of the
sorting algorithm instead of one version per elements kind.
