Martin Kustermann 10df757a49 [vm/ffi] Fix issue due to unspecified argument evaluation order in C++ 
We already have tests that exercise this, namely:

  - ffi_2/regress_39044_test
  - ffi_2/vmspecific_send_port_id_test

Though the bug only appears if C++ compiler decides to evaluate arguments
in a different order. This happens to be only the case on Windows.

We don't have Windows hardware with Android phones on our CI, which is
why this was not caught earlier.

We have manually confirmed (via building app on windows with this fix
and running on android) that the issue is fixed by this change.

Dart VM Compilation Pipeline

This folder contains Dart VM compilation pipeline.

Compilation pipeline is mainly responsible for converting AST or Kernel AST into IL flow graphs and then generating native code from IL.

It has the following structure:

Directory What goes there
assembler/ Assemblers and disassemblers
backend/ IL based compilation backend: optimization passes and architecture specific code generation rules
frontend/ Frontends responsible for converting AST into IL
jit/ JIT specific passes and compilation pipeline entry points
aot/ AOT specific passes and compilation pipeline entry points
. Shared code or code without clear designation.

Currently there are no layering restrictions and components from different subfolders can reference each other.
