Removes the result_size parameter in TFC definitions which
can be infered from the provided CallInterfaceDescriptor.

Previously, the result size was added to support stubs with
custom linkage. However, In pratice, the size don't differ from
the provided CallInterfaceDescriptor (given that it's a DCHECK)
and use mostly JS linkage (only one return).

This adds a new method Isolate::LocaleConfigurationChangeNotification
that clears the cached Locale allowing new Locales to be picked up in
later Locale operations.

It moves Date::DateTimeConfigurationChangeNotification to Isolate
(deprecating the old one) so that the configuration change methods are
found together.

TypedArray#join is now implemented Torque and was optimized in a way that no longer

Remove the duplication of the allocation logic via the
AllocateOneByteConsString and AllocateTwoByteConsString helpers, and
instead just have a diamond to figure out the result map. This reduces
code size of the StringAdd_CheckNone builtin and even seems to be
beneficial performance wise. It seems to improve the performance on
the `bench-dom-serialize.js` test by around 1% just doing this.

Drive-by-fix: Remove the `flags` from CodeStubAssembler::StringAdd()
and its helpers, since we no longer support pretenuring of string
additions (for quite a while now).

Also when running under simulator, cache_type_register_ is set to 0 explicitly

I thought about potentially adding the identifer ref to the error but
that would require allocating a new string or at the very least
increasing the size of the resulting cons string. Given that the
parser is pretty performance sensitive, I've decided to not display
the identifier.

Previously, the error was:
  _test.js:3: Error
  a[foo].c = () => { throw Error(); };
                     ^
  Error
    at a.(anonymous function).c (_test.js:3:26)
    at _test.js:5:1

With this patch, the error becomes:
  _test.js:3: Error
  a[foo].c = () => { throw Error(); };
                     ^
  Error
    at a.<computed>.c (_test.js:3:26)

This is a port of the improvements to the ArgumentsAdaptorTrampoline
that previously landed for x64. It skips the arguments adaptor frame
creation if the callee cannot observe the actual arguments (as indicated
by the "is_safe_to_skip_arguments_adaptor" bit on the SharedFunctionInfo),
and instead just massages the current stack frame appropriately (either
by pushing more undefineds in case of under application, or by removing
the superfluous arguments in case of over application).

Due to the 16 byte stack alignment requirement on arm64, we only skip
the arguments adaptor frame creation when the difference between the
expected and the actual argument number is even. When it is odd, we
would still need to copy the actual arguments in the existing frame to
account for the padding, which would defeat the point of the improvement.

This CL moves the following builtins from CSA to Torque:

TypedArray.prototype.forEach
TypedArray.prototype.reduce
TypedArray.prototype.reduceRight

A space-saving decision was made in the design -- instead of emitting
versions of the central loop for each ElementsKind, a function
pointer which knows how to read from the appropriate TypedArray
ElementsKind is constructed at the outset, and passed into the
loop. This enormously reduces codesize for the TypedArray builtins.
We'll have to see if the overhead of the builtin call affects
performance too adversely.

The interpreter is set up specially in cctests to allow more direct
testing. This requires sometimes to write special testing code in the
interpreter which is different than production code. This CL fixes one
instance of testing code which deals with indirect calls.

In production code, indirect calls go through the indirect function
table which can change over time. In cctests, however, the indirect
function table is not set up completely. In cctests the interpreter
uses information from the module instead to acquire the target of an
indirect call. In that testing code, calls to imported JS functions
were not handled. This handling gets added with this CL.
