kmillikin@google.com 25ac913c69 Remove the default contains_call parameter on location summaries. 
The plan is to use this parameter to make finer distinctions between
calls (e.g., safepoint vs. non-safepoint).  It's a bit safer to eliminate
the default.

vegorov@google.com 61dc368874 Fix kStoreBufferBlockProcessRuntimeEntry calling sequence. 
Poping of volatile registers was performed without taking into account the fact that stack pointer could have been  modified to ensure correct alignment _after_ volatile registers were pushed.

Enable --use-ssa on x64 again.

asiva@google.com 3107319e40 Simplify representation of stack frames. Remove the special types DartFrame/StubFrame and instead use StackFrame with methods IsDartFrame and IsStubFrame for frames representing Dart or Stub Code. This eliminates all the complexity that was added to ensure that we always see only one stub frame before hitting a dart frame during iteration. 
Fixes bug 6380625 which was another case when we had two stub frames before hitting the dart frame.
