Failures on [vm] Fix unwinding through FutureIterable and FutureRecordN wait

[liamappelbe]

There are new test failures on [vm] Fix unwinding through FutureIterable and FutureRecordN wait.

The tests

vm/dart/awaiter_stacks/async_stacks_test/1 RuntimeError (expected Pass)

are failing on configurations

vm-aot-obfuscate-linux-release-x64

Log: https://dart-ci.appspot.com/log/vm-aot-obfuscate-linux-release-x64/vm-aot-obfuscate-linux-release-x64/526/vm/dart/awaiter_stacks/async_stacks_test/1

Looks like this test is just a bit too strict about expecting a specific stringification of the stack trace

Summary: AOT obfuscated Linux x64 build fails async_stacks_test. The issue seems to be overly strict stack trace stringification in the test.

Looking at the output we seem to be leaking internal name mangling scheme for the extension methods: we get FutureIterable|get#wait instead of FutureIterable.wait which is expected there. I will take a look.
