Nathan Rogers ff13c4e31a [fuchsia] Avoid unnecessary zx_clock_get(ZX_CLOCK_THREAD, ...) calls 
When system tracing is enabled on the Fuchsia platform, avoid calling
|OS::GetCurrentThreadCPUMicros|.  The thread timestamp values are
discarded later, so querying them is wasteful w.r.t. both time and
trace buffer space.

Vyacheslav Egorov a9ce969e53 [vm] Decouple growable_array.h and zone.h from thread.h 
- Introduce a slimmed down version of thread.h, which just depends on the
Zone and StackResource.
- Introduce a layering check that would prevent the coupling in the future.

This is the first step towards decoupling compiler from runtime.

There are multiple reasons to introduce the decoupling but the main
reason currently is to introduce a controlled surface through which
compiler reaches into runtime to catch any places where runtime word size
might influence the compiler and then enable building compiler that
targets 32-bit runtime but is embedded into a 64-bit runtime.

Carlo Bernaschina ce736d3ef0 Add current rss and embedder name to Observatory 
Moved the responsibility to provide MaxRSS and CurrentRSS from the VM to
the embedder.

The embedder can opt-it by setting a Dart_GetEmbedderInformation
callback using the public Dart_SetEmbedderInformationCallback API.

The implementation of the Dart_GetEmbedderInformation should mandatory
fill the version field and the ones it is able to fill.
The name field must reference a constant C style string, it will not be
freed by the VM code.

Martin Kustermann ac8d2056a3 Fix asserts in StackFrameIterator which were effectively disabled 
The assertions which tried to assert that we only use
StackFrameIterator to walk frames of the current thread was incorrect.
We already have cases where other threads will walk the stack of the
mutator thread, see below for an example where this can happen.

Thread::VisitObjectPointers was incorrectly passing Thread::Current() to
the StackFrameIterator instead of 'this'.  (Code in thread_registry.cc will
loop over a number of threads and calls VisitObjectPointers on them)

  Mutator thread:

    0  pthread_cond_wait@@GLIBC_2.3.2
    1  dart::Monitor::WaitMicros
    2  dart::Monitor::Wait
    3  dart::MonitorLocker::Wait
    4  dart::ThreadBarrier::Sync
    5  dart::GCMarker::MarkObjects
    6  dart::PageSpace::MarkSweep
    7  dart::Heap::CollectOldSpaceGarbage
    8  dart::Heap::CollectNewSpaceGarbage
    9  dart::Heap::CollectGarbage
    10 dart::DN_HelperObject_<native>
    11 dart::BootstrapNatives::<native>
    <dart frames>

  MarkTask thread:

    1  dart::EntryFrame::VisitObjectPointers
    2  dart::Thread::VisitObjectPointers          <---- Walks mutator thread stack
    3  dart::ThreadRegistry::VisitObjectPointers  <---- Iterates over a number of threads
    4  dart::Isolate::VisitStackPointers

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.

Zach Anderson 22e449ba09 Fix Windows time zone name extraction. Update API docs 
On Windows, the OS provides a full name for the time zone
rather than an abbreviation. Further the string may
contain non-ASCII characters, so a conversion is
necessary. This CL updates the API docs to match the
actual behavior, and fixes the string conversion problem.
