These changes fix Python 3 compatibility errors in third-party libraries
I'm not sure if these problems can be fixed this way.
But! (1) In deps/inspector_protocol no file roll.py
it looks like the repository v8 it shouldn't be, either.
(2) I have not found a separate repository for binutils.

Constructors have been removed. Initialization syntax with {}
for structs and classes is now limited to the initialization
expressions for the fields, so "constructors" deviating from
that explicit and complete list of field initialization
values must be declared as separate macros.

This CL changes Array#sort to work roughly like:
1) Call [[Get]] on the receiver in [0, length) and store to FA
2) Use the existing TimSort to sort that FA
3) Call [[Set]] on the receiver in [0, length) using the result
This has the advantage that we no longer need different fast-paths
for the sorting algorithm itself, only for step 1 and 3. This results
in a code size reduction of ~2650 bytes.
This CL does not include optimizations that elides step 1 or 3.

Intrinsic changes:
- Rename %RawCast to %RawObjectCast and add error checking so that it
only applies to subtypes of Objects.
- Add %RawPointerCast, which is similar to %RawObjectCast but must be
used for all subtypes of RawPtr.
- Add %RawConstexprCast, which allows one constexpr to be be cast to
another at compile time. It translate to an appropriate static_cast
in the generated code
- Add %FromConstexpr, which handles most of the standard cases of
generating XXXConstant CSA nodes from constexpr constants. It uses
either SmiConstant, NumberConstant, StringConstant, IntPtrConstant
or Int32Constant, depending on the cast-to type generic <To> type.
- Add support for intrinsics that return constexpr results.
Cleanup:
- Turn FromConstexpr into a generic with two generic types, a <To> and
a <From> type. Most FromConstexpr can use the new %FromConstexpr
intrinsic rather than provide an explicit implementation.

The array length is modifiable by user code that is called as a
side-effect during the sorting algorithm. We thus cannot base any
guarantees on the current length, but must reference the initially-read
array length instead.
Note that even though the algorithm may read and write from beyond
the current array length value, this adheres to the spec, which only
requires accesses to be within the original array dimensions (i.e.: 0
<= i < original array length).

The implicit parameter syntax adds a second parameter list
before the explicit parameter list when declaring macros, builtins and
runtime functions:
extern macro MyMacro(implicit a: Smi)(b: Oddball);
when calling the macro, only the formal parameters can be provided
at the call site. The implicit parameters are implicitly looked-up
by name in the scope of the call and prepended to the explicit parameter
list. The values that are found by name for each implicit parameter must
be castable the corresponding implicit parameter type:
MyMacro(Null); // Error, a is not defined
...
const a: Smi = 0;
MyMacro(Null); // OK
...
const a: Object = 0;
MyMacro(Null); // Error, a has wrong type
For external macros, builtins and runtime functions, the formal
parameter list expected on the C++ side is the concatenation of the
implicit and explicit parameter lists.
As a drive-by: fix the formatting of typeswitch statements in the
the presence of deferred-marked blocks and funky white space.
