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.

Now it only forwards to logcat and the output is as expected.

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
    5  dart::Isolate::VisitObjectPointers
    6  dart::GCMarker::IterateRoots
    7  dart::MarkTask::Run
    8  dart::ThreadPool::Worker::Loop
    9  dart::ThreadPool::Worker::Main
    10 dart::ThreadStart

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.

Ryan Macnak 85cdc0eac2 Don't assume we want the iOS ABI if running simarm on Mac and the EABI otherwise. 
Allow controlling the target ABI by defining TARGET_ABI_IOS or TARGET_ABI_EABI.  If neither is defined, default to the previous behavior.

Make Linux, Mac, Android and iOS agree on the value of PreferredCodeAlignment for all architectures.
