Now that we always cache lookups through scope-info-backed scopes on the
entry-point scope-info-backed scope, we don't need additional caching
per scope-info. The one missing piece was negative lookups, but they
automatically turn into DynamicGlobals which we also cache on the entry
scope.
The one possible difference is that we don't cache across compilation,
but seems unlikely to be very beneficial. We'll keep an eye out for
regressions though.

This CL adds support for embedded builtins in nosnap builds by creating
and setting an 'embedded blob' after builtin generation. Unlike
snapshot builds, the blob is not embedded into the .text section but
located on the C++ heap.
This makes nosnap builds more consistent with mksnapshot, and allows us
to simplify there and in serializer cctests.
Complications arise from the different workflows we need to support:
1. the standard mksnapshot build process,
2. nosnap builds (which reuse the blob created by the first Isolate),
2. and tests with various complicated serialization workflows.
To cover all of these cases, this CL introduces two knobs to twiddle:
1. A 'sticky' embedded blob which overrides compiled-in default
embedded blobs at Isolate setup.
2. The blob lifecycle can be managed manually or through refcounting.
These are described in more detail in isolate.cc.

Moves the unicode predicate cache tables out of the unicode cache,
and turns them into generic predicates in char-predicates.h which
use static constexpr tables.
This drops the per-isolate cost of unicode caches, and removes the
need for accessing the unicode cache from most files. It does remove
the mutability of the cache, which means that there may be regressions
when parsing non-ASCII identifiers. Most likely the benefits to ASCII
identifiers/keywords will outweigh any non-ASCII costs.

This extracts the lambda tasks to an own compilation unit and header
file. Additionally, it addresses the TODO to avoid templates and just
store the function to execute in an std::function.
Third, it provides the same functionality for pure (non-cancellable
non-idle) tasks.
Last, it removes the "Lambda" part from the methods, because we can
actually instantiate it with anything that is invocable (function
pointer, lambda, functor, ...).

- Name lookup in module scopes has namespace semantics now: All
overloads from all parent modules are combined before overload
resolution.
- Allow overloads of different callables: runtime-functions,
macros, builtins, and generics.
- The duplication between the DeclarationVisitor and the
ImplementationVisitor is removed: The DeclarationVisitor creates
declarables for everything except for implicit generic specializations.
The ImplementationVisitor iterates over declarables.
The DeclarationVisitor only looks at the header of declarations, not
at the body.
- Modules become Declarable's, which will enable them to be nested.
- Modules replace the existing Scope chain mechanism, which will make it
easier to inline macros.
- The DeclarationVisitor and Declarations become stateless. All state is
moved to contextual variables and the GlobalContext.
- Implicit specializations are created directly from the
ImplementationVisitor. This will enable template parameter inference.
- As a consequence, the list of all builtins is only available after the
ImplementationVisitor has run. Thus GenerateBuiltinDefinitions has to
move to the ImplementationVisitor. Also, this makes it necessary to
resolve the link from function pointer types to example builtins only
at this point.

1) The CL extracts platform-specific code into separate files, see
https://docs.google.com/document/d/1HCgKIpdjy_CEodTLvZ5VuykDI6gGTHrTtau2j0zwm28.
Specifically this means:
* Move posix-specific API functions from v8.h to v8-wasm-trap-handler-posix.h.
Deprecate the existing TryHandleSignal API function.
* Move posix-specific function declarations from trap-handler-internal.h to
handler-inside-posix.h
* Move posix-specific function definitions from handler-shared.cc to
handler-outside-posix.cc
2) The CL changes filenames from *-linux.* to *-posix.*. I expect that
most of the implementation for MacOS will be the same as for Linux.

In a DCHECK inside SetPayload(), MSVC gives a C4806 warning. Use the
right types to avoid this.
Also add pointer-with-payload.h to BUILD.gn.

This CL gives a first look at the new way to represent tagged object
pointers in C++.
It adds infrastructure in Handles and the garbage collector to deal
with the new object type, and ports a first class to the new world.

GN should understand action outputs, so the header generated by the
run_torque action do not need to be separately listed in another
source_set.

as part of the continuing quest to get rid of Object*/Object**.
This is a fairly mechanical replacement of Object**/MaybeObject** with
wrapper objects carrying the same data. No change in behavior is intended.
Overloaded operators are provided to minimize code churn.

This is to prepare larger refactorings that reduce the amount of
information stored in the WasmCompilationUnits and avoid ever storing
the ModuleEnv. Instead, we will generate it when needed. This will
allow us to correctly switch from a trap-handler configuration to
non-trap-handler.

In the process:
- add volatile types for FastJSArray and remove the length_fast accessor
from JSArray with the application of more rigorous typing.
- add micro benchmarks for testing all the interesting slice cases
Also update a few assorted places in .tq code to make them more
idiomatic.
The original version of this patch had an overly agressive assert that has
been loosened.
