Alexander Markov 59cdc65dc7 [VM] Relax constraints for integer literals according to int64 spec
Handling of integer literals is corrected according to the informal spec
for the fixed-size integers:

https://github.com/dart-lang/sdk/blob/master/docs/language/informal/int64.md

This change allows unsigned 64-bit hexadecimal literals and MIN_INT64
to be used when running on the VM with --limit-ints-to-64-bits option.

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

    6  dart::PageSpace::MarkSweep
    7  dart::Heap::CollectOldSpaceGarbage

    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

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.
