2e36e9ea1e Don't use |v8_initializers| code in |v8_base|
Removing |CodeStubAssembler| from |v8_base| source list (see
https://chromium-review.googlesource.com/c/v8/v8/+/1346329) leads to
linkage problems with some build configurations because it was explicitly
and implicitly included in |v8_base| code.

This CL decouple this code and fixes problems.

f68ee6e7e4 [typedarrays] Use Detach instead of Neuter
This is purely a renaming change. The ES spec uses the term 'detach'
for the process of removing the backing store of a typed array, while
V8 uses the historical term 'neuter'. Update our internal implementation,
including method names and flag names, to match the spec.

Note that some error messages still use the term 'neuter' since error
messages are asserted by some embedder tests, like layout tests.

which asserted on calls to GetChars() that weren't in a
DisallowHeapAllocation scope, this CL takes a reference to the scope
in order to provide static protection in all builds.

7aac6bc905 [cleanup] Make unicode predicate cache tables static
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.

c696376e0b Reland [in-place weak refs] Fix MaybeObject function names
E.g., "ToWeakHeapObject" was misleading, since it didn't convert to a weak heap
object, instead returned a weakly pointed heap object. Change the function names
(in this case, to "GetHeapObjectIfWeak") to reflect this.

Also make casts explicit, if a MaybeObject is an Object, we can call cast<Object>().

13b899a5f9 [cleanup] Remove Isolate parameter from object print
With ReadOnlyRoots and GetIsolate on JSReceiver, we can remove almost
every isolate parameter from <Object>::Print. The remaining ones, like
Map, are special-caseable for read-only maps, and as a result we can
remove isolate parameters from <Object>::Print entirely.

This patch also opportunistically cleans up a few places where isolates
were only needed for Object::Print, such as TransitionAccessors and
DescriptorArrays.

bbbfd81cfc [torque] Turn implicit converts/unsafe_casts into generics
In the process:
  - Add strict ordering of Types so that name mangling is consistent
    and build time. Previously, the UnionType stored the union's
    types in a std::set<const Type*>, which did not have a consistent
    ordering of the types in the set.
  - Add a int31 type to enable consistency and correctness of
    handling of 'constexpr int31' values on the C++ side.
  - By removing the "implicit" keyword for operators, there is now
    one less difference between operators and calls, another
    incremental step in unifying operators and calls.
  - Enable external (i.e. C++-defined) generic specializations
  - Add CSA support for checking double ElementsKinds, including
    tests.
  - Clean up some constexpr/non-constexpr handling of ElementsKinds.

df2419039c Fix a Jumbo breakage
see crbug.com/841460 , we recently hit some build issues when using
Goma + jumbo builds because of a conflict on the definition of CONST,
v8 defines it in globals.h and including windows.h also defines it. It
should be possible to fix this by adding a bunch of #undef CONST but it
seems a little bit hacky and might not always work (this could only fix
the problem temporary if the jumbo merge limit changes and cause some
include files to get included in a different order).

Renaming the v8 definition of CONST to kConst, this follows the
style guide guidelines: "there is no reason to change old code to use
constant-style names, unless the old names are actually causing a
compile-time problem"
(https://google.github.io/styleguide/cppguide.html#Enumerator_Names)

I also had to turn the PropertyConstness enum into an enum class to
avoid some conflicts (both PropertyConstness and VariableMode define
kConst).
