Make CTX allocatable by the register allocator.
...
This change makes CTX available by not caching the current
context while in Dart code. Instead the current context
is held in a local variable (:saved_current_context_var) and
is passed as argument in CTX at calls.
This also simplifies a lot of code in the debugger: As a result,
Isolate::top_context is not needed anymore since the current context
can always be extracted from a Dart frame.

VM: Use current isolate as immediate operand in per-isolate stub code.

There is no need to load it from the context, if the stub
is per-isolate. This makes those stubs not rely on having a context in CTX,
and avoids loading the isolate pointer from memory.
This CL is part of the effort to free up CTX for general
allocation. Stubs that don't depend on a context in CTX
won't require storing the current context before calling
them.

Fixes to run "Hello, world!" on arm64 hardware.
...
Primarily, in Dart code, instead of using R31 as our
stack pointer, on entry we copy it into a second
register (R18) and use that as our stack pointer after
moving R31 to the Dart stack limit. On calling back
into C++ from Dart code, R31 is restored, and R18 is
cached in the callee-saved register R26.

Reduce CPU usage when no isolates need to be profiled (e.g. when an isolate calls readLineSync or sleep the isolate owns the thread but is blocked).
...
This CL does the following:
- Introduces two new API entry points: Dart_IsolateBlocked and Dart_IsolateUnblocked.
- The thread interrupter thread goes into a deep sleep if no isolates need to be profiled (not scheduled on a thread or are in a blocking call).
- When an isolate unblocks, the thread interrupter thread resumes regular interrupts.
- dart:io readLineSync and sleep mark that they are making a blocking call.
This fixes https://code.google.com/p/dart/issues/detail?id=18126 reducing CPU usage to 0% when waiting for stdin or sleeping.

Add pause/resume for isolates in vmservice/observatory.
...
Improve the isolate view and isolate summary.
Details:
- Rig DbgMsgQueueList so it can run even when the debugger hasn't started.
- Add <action-link> element for pause/resume actions.
- Introduce new flex-percentile css classes.
- Add <isolate-run-state>, <isolate-location>, <isolate-shared-summary>, and <isolate-counter-chart> elements. Counters are now displayed as a pie chart instead of as text.
- Reorg <isolate-view> and <isolate-summary> substantially.
- Add shared style sheet to <script-view>.
- Combine pause-on-start/pause-on-exit with other debugger pause events and present a consistent representation for these in the vm service. Reorg how pause events are shown in <isolate-run-state>.
- Give the user a nicer message when an isolate is still loading.
- Move the /resume command to /debug/resume. Implement this with a bool in the Isolate class which is used to smuggle resume requests from the vm service to the dart embedding api.
- Add the /debug/pause command to the vm service
- Break the DebuggerEvent struct out into its own top-level class. Add JSON printing.
etc.

Refactor 'dart:profiler' UserTag API
...
- Each isolate starts off with a 'Default' UserTag set.
- A null tag cannot be set.
- Calls to clearCurrentTag() should be replaced with a call to UserTag.defaultTag.makeCurrent().
- makeCurrent returns the previously current tag.
This allows for the following pattern to work:
callee() {
var old = calleeTag.makeCurrent();
...
old.makeCurrent();
}
caller() {
var old = callerTag.makeCurrent();
...
callee();
assert(getCurrentTag() == callerTag);
...
old.makeCurrent();
}

Fix edge case where profiler would miss the caller of the top frame.
...
Some stubs (and intrinsics) do not push a frame onto the stack leaving
the frame pointer in the caller.
PC -> STUB
FP -> DART3 <-+
DART2 <-| <- TOP FRAME RETURN ADDRESS.
DART1 <-|
.....
In this case, traversing the linked stack frames will not collect a PC
inside DART3. The stack will incorrectly be: STUB, DART2, DART1.
In Dart code, after pushing the FP onto the stack, an IP in the current
function is pushed onto the stack as well. This stack slot is called
the PC marker. We can use the PC marker to insert DART3 into the stack
so that it will correctly be: STUB, DART3, DART2, DART1. Note the
inserted PC may not accurately reflect the true return address from STUB.

Implement new stacktrace and deoptimization stress testing flags:
...
--deoptimize-every=N
--deoptimize-filter=FunctionName
--stacktrace-every=N
--stacktrace-filter=FunctionName
Add a word of stack_overflow_flags to the Isolate. Use a bit in this
word to indicate whether or not a function is being compiler for OSR.
This allows us to distinguish an OSR overflow from a stress-testing
overflow.
