Just a refactoring to make clear that we are talking about function
names. Note that there are also names for locals inside functions,
which we currently don't use.
Drive-by: Remove style-guide violation by {WasmModule::names_} field.

Commit edec05ea73
Usage of Print function was not consistent with it's signature,
which caused failures in compilation.
Original commit message:
`All Object::Print functions now take an Isolate* parameter. Various
XX::XXPrint functions now take an Isolate if it's needed rather than
calling GetIsolate(). Such method use DECL_PRINTER_WITH_ISOLATE rather
than DECL_PRINTER.
The _v8_internal_Print_ function (intended for use in gdb) now uses
Isolate::Current() to get hold of an Isolate.
Reduces the GetIsolate and GetHeap count by 9 and 5 respectively.
Also removes unneeded gdb/lldb macros (along with their support
functions), jfv, jfm, jda and jta, since job does the same thing.`

Instead of storing both the {NativeModule} and the {WasmModule} in a
{Managed} object, just store the {WasmModule} in the {NativeModule}
directly. This fixes crashes that happen if the {Managed<WasmModule>}

We currently store the protected instructions per code object in a
{std::unique_ptr<std::vector<ProtectedInstructionData>>}. This wastes
memory, because it requires two heap allocations, plus the vector might
over-allocate (and it currently does, because it is filled dynamically
during compilation).
This CL changes that to store the protected instructions in an
{OwnedVector}. This requires one copy after generating the list of
{ProtectedInstructionData} in an {std::vector} during compilation, but
saves memory afterwards.

Each local ABT is logically for one page. We passed the space in to the
constructor, but this is wrong because the space a page is in can
change, e.g. for compaction pages.
Instead, pass the page to the local ABT constructor and always get the
space from this. To do this we need to push the AllocateLocalTracker()
helper and friends down to Page, rather than its superclass MemoryChunk.
Unfortunately, we need to keep ReleaseLocalTracker() on MemoryChunk even
though only Pages can have local trackers, because we can't do virtual
dispatch on MemoryChunk::ReleaseAllocatedMemory() which would allow us
to clean up the tracker memory nicely for pages only.
We also have to make sure we update external bytes accounting properly
when swapping spaces, as in SemiSpace::Swap().

I am working on moving the wasm wire bytes off the JS heap, and hence

Some cctests force fresh creation of heap constants, even though the
cctest binary itself is an embedded snapshot build (i.e.: a snapshot
blob exists, and a binary-embedded blob exists). This breaks a few
assumptions, for example that off-heap builtins have a single,
canonical off-heap code range.
Unfortunately this isn't that easy to fix. I see a few alternatives:
1. In builtins setup, if an embedded blob exists, regenerate the
builtins for their metadata (things like the safepoint table offset),
and then replace them by off-heap trampolines.
2. As above, but deserialize the trampolines from the snapshot blob.
3. As above, but pack required metadata into the embedded blob and
create trampolines from there.
4. Act as if the embedded blob does not exist.
Alternative 1 does not work because the generated code can be slightly
different at at runtime vs. mksnapshot-time. Alternative 2 is out
because we do not have access to the snapshot blob in TestIsolate
setup. Alternative 3 is probably the preferred option but would be a
more involved change.
This CL takes path 4. It's not an optimal solution, but it can be
replace by alternative 3 later.

Currently each isolate stores its own array of
{CallInterfaceDescriptorData}. This array has size 173, and each entry
has 40 bytes. That's already 7kB per isolate.
Additionally, each {CallInterfaceDescriptorData} allocates two
heap-allocated arrays, which probably add up to more than the static
size of the {CallInterfaceDescriptorData}. Note that all the
{CallInterfaceDescriptorData} instances are initialized eagerly on
isolate creation.
Since {CallInterfaceDescriptor} is totally isolate independent itself,
this CL refactors the current design to avoid a copy of them per
isolate, and instead shares them process-wide. Still, we need to free
the allocated heap arrays when the last isolate dies to avoid leaks.
This can probably be refactored later by statically initializing more
and avoiding the heap allocations all together.
This refactoring will also allow us to use {CallInterfaceDescriptor}s
from wasm background compilation threads, which are not bound to any
isolate.

We currently have a system where the protected instructions are
unregistered when the last instance dies, and registered again on the
next instantiation. This is triggered by {WasmCompiledModule::Reset}.
Since the reference to the {NativeModule} will move to the
{WasmModuleObject}, and this object stays alive even if the last
instance dies, this will become hard to maintain.
It will also make it harder to share wasm code across isolates.
This CL refactors this to register trap handler data once when the code

We currently create a managed object holding a shared reference to the
WasmModule, and pass this to the factory method for the
WasmModuleObject. Instead, we can just create it inside that factory
method, removing code duplication.

"internal state" separate from the JS-facing {WasmModuleObject}. Since
this objective has no real value, and we already store some internal
data on the {WasmModuleObject}, this CL merges these two objects.

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.

> [array] Implement Array.p.sort in Torque
>
> This CL implements a generic baseline version and 3 fastpaths, for
> various elements kinds, of Array.p.sort in Torque. Details can be found
> in the Design Doc: https://goo.gl/Ge321G.
>
> Performance impact on micro benchmarks depends on the element kind
> and whether the user provides a comparison function.
> For HoleySmi/HoleyElement we have a speedup between 1.5-1.8 across
> the board. For Dictionary we are slower in all micro benchmarks (0.7).
> For PackedSmi it depends on the call site and whether or not a
> comparison function is used.
