Ryan Macnak 877284947b Rename TARGET_OS_* to HOST_OS_*.
Like HOST_ARCH_*, HOST_OS_* describes the OS the VM is running on, which may be different from the OS the VM is generating code for during AOT compilation.

Currently we conflate the two when emitting AOT as assembly, and we get away with it because Flutter only uses assembly for targeting iOS and one can only target iOS from a Mac, but we expect to use assembly for Android as well so native tools can unwind Dart frames.

Jens Johansen 137b85c114 Hide kernel isolate from isolate list; do not register it either
This is basically a copy of https://codereview.chromium.org/2689563010/
and https://codereview.chromium.org/2695013002/ - just hiding the kernel
isolate too.
That way, we won't see it and be confused when debugging via observatory.
Also, service tests could probably start working with the kernel isolate
too.

Still show isolate if passing "--show_kernel_isolate" though.

Original CL: https://codereview.chromium.org/2692803006/

Original commit message:
Tracking the awaiter return call stack:

- [x] Each async function closure now knows who is awaiting on their
return. This is effectively the asynchronous equivalent of the 'frame pointer'.
- [x] Each async* function closure now knows how is listening on their
stream. This is effectively the asynchronous equivalent of the 'frame pointer'.

Detecting uncaught exceptions in async functions:

- [x] Code object keeps a map from :await_jump_var to token position
- [x] Exception Handlers keep track if they are generated (as part of compilation) or directly from user code
- [x] Debugger maps :await_jump_var to a specific try index

Regis Crelier 3633c5bd5e Rename Closure instance field type_arguments_ to instantiator_.
Simplify handling of closures as deferred objects.
The name "type_arguments_" is confusing, because class Closure is not generic.
Class Closure was forcefully made (kinda) generic by setting its
type_arguments_field_offset_in_words_ field to a valid value, so that the
type_arguments_ field in closure instances could be accessed similarly as in
generic instances. With generic functions, closures will potentially have more
than one instantiator and the name type_arguments_ becomes nonsensical.

Vyacheslav Egorov 364b8575de VM: Restore old implementation of ClassID.cid* fields.
When we were implementing bootstraping from Kernel in https://github.com/dart-lang/sdk/commit/23fd1a184b393825f29444243780f3593ce0b3c1 we switched ClassID.cid* fields to become 'static final' lazily initialized fields instead of constants as they were before. This was mainly done to allow dartk compile patched_sdk - because these fields were previously injected in runtime and never existed in the text form.

However this regressed code quality for app-jit and app-aot snapshots because 'static final' fields are reset by snapshotting so resulting code contains InitStaticField and LoadStaticField instructions.

John McCutchan a0ee5b24db Track async causal stack traces
This CL improves the stack traces that accompany exceptions. Whenever an
async function is entered, we remember how we got there. This is similar
in spirit to package:stack_trace but the implementation is more efficient
and memory usage can be more easily reasoned about.

Tracking causal stack traces:

- [x] Upon entry to an async function, capture the synchronous stack trace prefix and store it into the closure.
- [x] Upon entry to an async* function, capture the synchronous stack trace prefix and store it into the closure.
- [x] Before returning from an async function, clear the Thread's asynchronous stack trace.
- [x] After resuming an async function, load the sychronous stack trace prefix into the Thread.
- [x] Filter stack traces to remove async machinery.

Service protocol changes:

- [x] Send causal async stack trace.

Observatory changes:

- [x] Display causal async stack trace below async functions.

Kevin Millikin fdb4c100e0 Move _fatal from dart:core to dart:_internal
_fatal was a private function in dart:core which was called from a
different library (dart:async).  It's not clear how it was supposed to
work or if it even did.  The uses in dart:async don't appear to be
covered by tests.

Move it to dart:_internal which exists exactly for sharing things
between the dart: libraries.

Martin Kustermann e97bcc5475 VM: [Kernel] Partial support for metadata annotations
The CL adds metadata support for Fields/Classes/Functions/Constructors. There
are other places where annotations can be put in the Dart language but the
Kernel IR currently does not store it in the AST.

Whenever a element (e.g. a function) gets annotated, the VM will make a [Field] for this
element whos value is an array of evaluated constant metadata annotations.

This CL attaches to these [Fields] a `kernel_function` which is then used to do the constant
evaluation.
