It relies on flutter copy of clang distribution, same one that is used to build flutter/engine.
It addressed several deprecated warnings from clang compiler for functions like strdup, unlink, etc.
It allows few warnings still since they are triggered in third_party sources.

Background:
on the latest versions of iOS today, we have to use mdns to discover the observatory port and authentication code. For a variety of reasons this can fail, leaving us with no way to connect.
An alternative approach is to specify the observatory port and disable the authentication code. If binding to this port fails, however, we would still like to attempt connecting with mdns.
Overview:
This adds a new flag to the dart SDK, --enable-service-port-fallback. This amends the behavior of the vmservice with a specified port. After failing to bind 3 times to a non-zero port, update the port selection to 0.
Results:
Tested locally two dart VMs with the same specified port:
```
jonahwilliams@jonahwilliams0:~/Documents/engine/src/out/host_debug_unopt$ ./dart --enable-service-port-fallback --observe=8080 example.dart
Observatory server failed to start after 1 tries
Falling back to automatic port selection
vm-service: isolate(2785434094928835) 'main' has no debugger attached and is paused at exit. Connect to Observatory to debug.

Previously, a valid web socket connection would use the following URI:
`ws://127.0.0.1/ws`
Now, by default, the VM service requires a connection to be made with a
URI similar to the following:
`ws://127.0.0.1:8181/Ug_U0QVsqFs=/ws`
where `Ug_U0QVsqFs` is an authentication code generated and shared by the
service.
This behavior can be disabled with the `--disable-service-auth-codes`
flag.

This enables other emdedders to reuse parts of the standalone embedder
implementation without depending too much on the implementations details.
As part of the change we also remove a dependency from DartUtils on
IsolateData - by removing dart:_builtin library caching. Lookup
of this library does not seem to be on hot path anymore in Kernel world.

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.

Review URL: https://codereview.chromium.org/2438613002 .
We now check all of the scripts which make up a library. If any
script is modified, then we consider that library to be modified. We
also consider any library which imports a modified library to be
modified. To propagate this info efficiently, we build and discard
the imported-by graph when beginning a reload.
The embedder must provide a FileModifiedCallback in order to support
the detection of modified scripts.
In order to detect changes to package: libraries, we have modified the
embedder interface to provide the resolved url when possible, so that
we don't need to re-resolve package uris when checking for reload.
This change is incompatible and all embedders will need to be updated.
We now support a "force" flag when reloading sources. This causes all
libraries to be reloaded regardless of whether the underlying scripts
have been updated.

Remove -fdata-section again from the Linux build configuration: It prevented
some optimizations in gcc and clang - fewer things were recognized as constants.
Add const to pointers/arrays in some places to help compilers with determining
what is a constant. A common pattern is strlen of a string literal const char*,
or an array of function pointers.
Tested with gcc 4.8.4 / clang 3.4 and improves code qualtiy + reduces binary size.
