fschneider@google.com 13b7b7242a Faster invocation of fields as methods.
Until now there was a large discrepancy between

x.f() and
(x.f)()

This CL makes x.f() as fast as (x.f)() by automatically
generating  a intermediate dispatcher function that loads
the field and invokes the result as a closure.

The approach resembles the one taken for fast noSuchMethod
invocation and reuses the same per-class cache
of dispatcher functions.

It also fixes a bug in the debugger so that VM-generated 
implicit dispatcher functions (like for noSuchMethod, or
field-as-method invocation) don't show up the debuggers
stack trace.

fschneider@google.com d77d1eac90 Correct handling of named optional parameters with noSuchMethod invocations.
This CL fixes a performance bug with noSuchMethod and named parameters. It also
simplifies the platform-specific code by removing special casing for the
noSuchMethod-dispatcher functions in the flow graph compiler.

Before using named optional parameters would still go through the slow
runtime in certain conditions: When running without inlining, or when
the dispatcher function was not inlined because of e.g. inlining size
heuristics, noSuchMethod would be slow if invoked with named parameters.

fschneider@google.com f260416fb8 Support fast noSuchMethod dispatch for any number of arguments.
Until now, the fast dispatch was only available with getters and
zero argument methods.

This CL generalizes the approach to any number of arguments. The
dispatcher functions that are auto-generated by the compiler
are not attached to the class anymore. Instead the dispatcher
is only stored in the IC data of each call site. Each class
contains a cache of dispatcher function that map
(name, arguments descriptor) => dispatcher.

This also fixes a bug where the VM report a wrong error message
when throwing a NoSuchMethodError.

This change adds code that detects if an expression can definitively
never be constant. We use this to analyze the initializer expressions
in const constructors. This check is not entirely water tight, but
together with the checks in canonicalization code catches most
illegal initializer expressions.

The const constructor of class Symbol turns out to be illegal. The
name verification check can't be part of the constructor code.

This is the same CL as https://codereview.chromium.org/17315008/ with
one bug fixed:

If a method is invoked with a mismatching number of arguments, we don't
add a no-such-method-dispatcher function since the dispatcher currently
can only invoke noSuchMethod and would not work if the method
is invoked with correct arguments at a later point.

I extended the test to cover that case.

fschneider@google.com ab1981b421 Optimizing noSuchMethod invocation with no arguments.
On each call that triggers a noSuchMethod invocation we 
attach a custom dispatch function that allocates the 
invocation object and invokes noSuchMethod. This dispatcher
is compiled and optimized like a normal Dart function.

Similar to method-extractors, these implicit dispatchers
do not show up as normal functions.

As a first step this CL only handles invocations of getters
and methods with no like o.foo or o.foo().  This CL gives
a >25x speedup of such noSuchMethod invocations. Calls with
multiple arguments still go through the slow path.

asiva@google.com 3f97d1492a More cleanup to avoid creation of redundant handles
- create read only handles for null object and sentinel smi value
- add a RawCast function to allow direct casting of Raw pointers without the
  need to create a Handle for it
- use Smi::Value where possible
- hoist out handle creation from some loops

iposva@google.com 1836035266 - Modify dart_api.h to be a proper C API.
- Verify that dart_api.h can be used from C
  by changing the test_extension to be a pure C file.

fschneider@google.com 9a6657cd4d Eliminate temporary locals for some expressions
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.

srdjan@google.com d1adfc37a3 Fix issue 3874: non-deterministic AST generation caused by exceptions being thrown during parsing (StackOverFlow). Mark functions that throw and exception as non-optimizable.
Fix flow graph printing (optimized vs non-optimized).

fschneider@google.com fa9885005a Remove pseudo-node from LoadLocalNode and replace it with a proper AST node.
The newly introduces CommaNode denotes a sequence of two nodes, the result
is the value of the second child node.

There are only two places where the pseudo-node was used, and therefore
it does not warrant adding an extra member to all LoadLocalNode objects.

X64:
Size of isolate snapshot = 1223943
