Update VM to latest spec. Referencing a name that is imported
from more than one library is no longer a compile-time error.
If one of the sources of an ambiguous reference is a dart library,
the dart library declaration is automatically hidden.
Also fixes a bug where looking up a getter name in a library
found the getter even though the name is filtered out in the
'hide' combinator.
Long-term we should fix the need for repeatedly convert between
the mangled getter and setter names and the untangled name.
Fixes 12915, 12913, 12724.

The Name function is used for pretty printing except that for a few
node types we rely on a specific name for implementation correctness.
Overriding the pretty printing function to get out a type name, or a
variable name, or an operator symbol name, is risky.
1. Code that relies on the semantics of the name will break if the
pretty name is changed.
2. Pretty printing is less useful. For instance, LoadLocalNode just
prints the variable name (twice, once as the AST constructor and
once in quotes as the variable name). This is confusing if the
variable happens to have the same name as one of the other pretty
names, e.g., args or seq.
Now, there is a virtual function to get the pretty name but classes do
not change it to communicate other information (type names, variable
names, operator names).

Instead of having a separate IL instructions relational comparisons
are built as normal instance calls initially. When optimized, we replace
the instance call with a smi/double/mint comparison instruction.
This enables generic inlining of relational operator calls and simplifies
code generation, too.
Merging comparisons with branches is done in the optimizing compiler's
branch simplification phase.

This works because I changed the compiler so that it always emit
the full unoptimized code for all intrinsic methods in a previous CL
As a result deoptimization works for those methods like for normal
methods.
Also, code for some recognized getter methods is moved to the flow
graph builder, so that there is no need for special handling in
the flow graph optimizer. This part of the change is
should be performance-neutral.

Add test.
Update status files.
Explanation of change: A malbounded type argument should not be mapped to
dynamic, as is a malformed type argument.
This change also adds a bunch of TODOs related to the encounter of malbounded
types in unexpected places.
A follow-up change will address these TODOs, add more tests, and may simplify
code that is still handling malformed types where they cannot occur anymore
after the spec simplified their handling.

The optimizing compiler currently recognizes a certain frequent native methods
like array length or string length and provides an inlined implementation.
Inlining does currently not work for polymorphic call sites of these methods.
This CL enables also polymorphic inlining in the case of .length getters for
arrays and strings.
1. The method is recognized at flow graph build time. The builder creates
the body of the method for both compilers (non-optimizing and optimizing).
Native methods that are not recognized, are translated as before using a NativeCall
IL instruction.
2. The flow graph inliner handles recognized methods in the same manner as normal methods.
Until now intrinsic and recognized method could not be inlined. This CL enables it.
3. There is no need for an intrinsic assembly implementation because recognized methods
have an IL implementation that does not call into the C++ runtime. I left the intrinsics
in for now, but they can be removed if there is not noticable performance benefit anymore.
4. The inlining heuristics are tweaked in a way that enables more aggressive inlining
of recognized methods: +1 level of inlining depths, call sites of recognized methods are
not counted in the inlining heuristic.

When nesting try-finally, the outer finally was incorrectly executed
twice under certain conditions (a return in the inner try-block and a outer
finally-block that ends with throw)
This was because finally-code was inlined at return/break/continue statements
and it was associated with the wrong catch-handler when compiling.
This CL tracks indices of try-blocks in the parser so that each inlined
finally block has the correct catch handler index.

In optimized code we can eliminate the allocation of closures that are not
escaping and where all calls are inlined.
Closures are currently allocated with a special IL instruction (CreateClosure).
This CL changes this for non-implicit closures and allocates them
like normal objects. The fields for the function and the context are
initialized like instance fields. This way object allocation sinking can
handle closures like any other objects.

This CL removes the remaining missing cases when inlining closure
calls.
In order to benefit for code using forEach, I added GrowableObjectArray.forEach
to the functions that should always be inlined.
I also renamed BuildLoadContext/BuildStoreContext helpers in the flow
graph builder to better match what they do.

Add profiling support to select OSR candidates and launch the compiler
for OSR, followed by entry to the function at the OSR entry point.
Implemented only on IA32 and X64. The initial implementation can be
improved in various ways --- specifically: tuning of profiling
parameters and incorporation of feedback about the actual values seen
at OSR entry.

1. The result value of an expression
"super.someMissingSetter = val" was incorrect in case of a noSuchMethod call.
To fix this I refactored the BuildStaticNoSuchMethod function. It now no longer
creates AST nodes and visits them, because the last argument may be needed saved
as a result value.
2. The evaluation order of "super[e1] = e2" was wrong in case of a noSuchMethod call.

This CL affects a subset of expressions that use temporary locals: constructor
calls, array literals and and instance getter postfix-ops.
For expressions that are de-sugared in the parser I added LetNode.
It creates a scoped temporary local bound to an initializing expression.
For expressions where we need a temporary local at graph-building time,
I added a helper class TempLocalScope to easily create a single temporary
local in the graph builder since this is a frequently recurring pattern.
This simplifies code in the parser and the graph builder and also fixes a
bug with indexed-super invocation and NoSuchMethod.

Two parts:
1. Change AllocateObjectWithBoundsCheck to a normal call that takes
four arguments on the stack using PushArgument IL instructions.
Before inputs were in registers and the instruction pushed them itself
before the runtime call. This make the code more compact and simplifies
the flow graph builder.
2. Simplify instructions for building constructor type arguments for another
special case to simplify the instruction pattern and generate smaller
code for that case.
