4b0f9c856e [cleanup] Use Vector::begin instead of Vector::start
Our {Vector} template provides both {start} and {begin} methods. They
return exactly the same value. Since the {begin} method is needed for
iteration, and is also what standard containers provide, this CL
switches all uses of the {start} method to use {begin} instead.

Patchset 1 was auto-generated by using this clang AST matcher:
    callExpr(
        callee(
          cxxMethodDecl(
            hasName("start"),
            ofClass(hasName("v8::internal::Vector")))
        ),
        argumentCountIs(0))

Patchset 2 was created by running clang-format. Patchset 3 then
removes the now unused {Vector::start} method.

c5f5b93d9b Remove Vector constructor accepting static array
Use the existing {ArrayVector} method for this, which reads nicer. In
some places, I replaced a stack-allocated array by {EmbeddedVector} to
avoid the {ArrayVector} call.

6cac1382f4 [cleanup] #include heap-inl.h less often
This takes heap-inl.h out of the "Giant Include Cluster".
Naturally, that means adding a bunch of explicit includes
in a bunch of places that relied on transitively including
them before.
As of this patch, no header file outside src/heap/ includes
heap-inl.h.

455200e009 [cleanup] Move some stuff out of objects-inl.h
HeapObject::SizeFromMap() was too large to get inlined anyway.
HeapObject::IsFoo() predicates should be implemented in foo-inl.h,
because that's what they depend on.
This patch also fixes up includes: dropping unnecessary ones from
object-inl.h, and adding them in other places that previously
relied on getting them transitively.

592aeefa8d Defer inferring language mode as far as possible
Inferring the language mode involves iterating the stack to find the
closure. This is an expensive operation and should be done only when
required. This cl changes the implementation to infer the language
mode only when we can't defer it any further. Currently, we infer the
language mode when throwing an exception or when passing this
information to PropertyCallbackArguments.

This cl also changes the language mode parameter to SetProperty
related methods to Maybe<ShouldThrow>. We only use the language mode to
decide if we need to throw and using ShouldThrow instead of language
mode simplifies the code by avoiding conversions from Maybe<ShouldThrow>
to Maybe<LanguageMode> and vice-versa.

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.

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.
