Instead of calling code object directly, call indirectly and
pass the code object in a register. The object pool is then loaded from
the code object. This is another preparation step for making generated code
relocatable.
All non-ia32 platforms:
No entry patching.
ARM:
PC marker (now code object) moves to the same place as on x64 (below saved PP, above saved FP).
R9 is now used as PP, R10 as CODE_REG.

- TEST_CASE now passes the current thread as a parameter to the unit test.

This makes the test code independent of the way we call Dart code and
makes it easier to change the calling convention.
The code for calling test code is now encapsulated in unit_test.h instead
of being spread over many different files.
I only changed the tests that need a constant pool set up, but the same strategy
could be used for all other assembler tests to avoid unnecessary duplicated
boilerplate code.

- Complete revamp of isolate-specific flags.
- Associate flags with the isolate on creation.
- Dart_CreateIsolate and associate callback do take an
extra flags argument.
- Make sure to clear IC data array when clearing code.

In addition to tracking input and output ranges in the IC-stubs with a Smi fastpath (SmiAdd and SmiSub, currently) this CL also introduces two IC stubs that have no fast-path by still track ranges and update the range feedback.
We are able to distinguish between the following ranges (encoding of the lattice is shown in the parens):
- u-smi (0000)
- smi (0001)
- uint31 (0010)
- int32 (0011)
- uint32 (0100)
- int64 (1xxx) and (x1x1)

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.

compatible with webkit and will allow for easy externalization of
strings. One byte strings are retained for pure ASCII strings.
(The language specification was changed recently to reflect this as
follows "A string is a sequence of UTF-16 code units").
- Remove four byte string class and all references to it.
- Rename some of the string functions in Dart API to make them
consistent and better describe the underlying functionality

launch an isolate running a different script. Finally.
Reviewers: This isn't as hard to review as it looks. Dive right in!
Siggi: Take a look at my test status file changes and make sure I'm
excluding the right stuff.
Much of the churn in the CL comes from moving ownership of the
import_map. It used to be set per-library and is now set per-isolate.
This caused a lot of superficial diffs.
DART EMBEDDING API CHANGES:
- Dart_IsolateCreateCallback now takes a script_uri and main argument
instead of a name_prefix argument. The script_uri argument allows
the callback to launch different scripts. The main argument is used
in creating the isolate debug name.
- Dart_CreateIsolate now takes script_uri and main arguments. These
are used to build the isolate's debug name.
- Dart_LibraryTagHandler, Dart_LoadScript, and Dart_LoadLibrary no
longer take an import_map.
- Added Dart_SetImportMap.
- Added Dart_RootLibrary to provide access to the root library for the
current isolate.
OTHER STUFF
Add a couple of tests for spawnUri -- the existing tests assume that
scripts end in a .js suffix which isn't going to work out for us.
Changed how the debug name for isolates get built a bit.
Refactored bin/main.cc a bit. Fixed some problems with error handling
while creating isolates.
Minor refactoring in builtin.dart to always pass is_windows rather
than relying on it being squirreled away.
