asiva 5399dbf6f6 [VM/dartdev] Switch dartdev to use an AOT runtime.
- split the Dart CLI tool out of the VM into it's own embedder which
  runs in AOT mode. The pure Dart VM executable is called 'dartvm' and
  has no Dart CLI functionality in it
- the Dart CLI executable parses the CLI commands and invokes the rest
  of the AOT tools in the same process, for the 'run' and 'test'
  commands it execs a process which runs 'dartvm' to run
- 'dart hello.dart' execs the 'dartvm' process and runs 'hello.dart'
- the Dart CLI is not generated for ia32 as we are not shipping a
  Dart SDK for ia32 anymore (support to execute the 'dartvm' for ia32
  architecture is retained)
- the Dart CLI tool is not built in the internal Dart SDK builds

Martin Kustermann 698bf0846b [vm] Hoist CStringUniquePtr out of Utils, add CAllocUniquePtr` to simplify code
Hoist `CStringUniquePtr` out of the `Utils` class as there
is no reason it has to be nested inside a class - it just makes
code more verbose.

This simplifies code of the form
   std::unique_ptr<T, decltype(std::free)> a = { nullptr, std::free };
to
   CAllocUniquePtr<T> a;

Slava Egorov c2e9ceeb6b [vm/io] Cleanup long path handling on Windows
* Switch to `std::unique_ptr<wchar_t[]>` to represent a
dynamically strings instead of wrappers like
`StringRAII` and `Utf8ToWideScope`;
* Avoid back and forth conversion between UTF8 and UTF16:
convert to UTF16 first then work on that. This also simplifies
code - previously it tried to work with strings allocated in
different ways uniformly, which is actually unnecessary if
resulting string needs to be converted to UTF16 (and allocated
with `malloc`) anyway;
* Fix a bug in `File::CreateLink`: it was handling relative
links with long paths incorrectly. Change file_long_path_test
to cover this case and make it run on non-Windows systems as
well to ensure that all behavior that can match actually
matches.

Zach Anderson bc07953866 [dart:io][windows] Make unicode characters display correctly.
This change has two pieces.
- Set the console code page to UTF8.
  - This makes strings printed with print() display correctly
- Set the file translation mode to _O_WTEXT when writing to a
  stdout or stderr that is connected to a console.
  - This makes strings printed with e.g. stdout.writeln()
    display correctly.

Zach Anderson b6ea87c444 [windows] Make most file_win.cc functions use malloc for string conversions.
They have been using Dart_ScopeAllocate(), which makes them impossible

Also turn on inlining in the GN Debug windows build to match the gyp build
and speed things up a bit.

Also some style cleanups.

Decided to fix these leaks by using Dart_ScopeAllocate
instead of malloc and new. Leaks are noted in the CL.

I haven't finished looking over all the code in
//runtime/bin yet, but this CL was getting big.
