ricow@google.com 3cf4ca80ce Speculative fix for android build. 
It is really hard to follow the directory logic, with DART_DIR being just ../../.. and a few pushd and cd commands thrown in.

I don't particularly like this solution either, this is basically to verify that I am assuming correctly in that this is caused by the relative paths being messed up.

vegorov@google.com 2565ca222f Implement a variation of scalar replacement for non-escaping allocations. 
AllocationSinking pass discovers non-escaping allocations that have no input uses other than uses in the stores into its own fields.

Every environment use of such allocation is replaced by a state snapshot (MaterializeObject instruction) that describes the state of each initialized field in the object. State snapshots are computed through an additional round of load-forwarding.

Once snapshots are computed allocations are removed from the graph.

MaterializeObject instructions are not compiled into native code but produce deoptimization instructions instead that describe how object should be materialized at deoptimization.

Deoptimization instructions now follow the following format:

[mat obj #1]...[mat obj #N][ret addr][... mat arguments ...][... real frames ...]

- the prefix describes each object to materialize on deopt via kMaterializeObject instruction;
- actual values that are needed for materialization are emited as a part of bottom-most stack frame. This is done to simplify implementation: they need to be discoverable by a GC during materialization phase. At the end of deoptimization they will be removed from the stack;
- normal stack slots can refer to materialized objects via kMaterializedObjectRef instruction.

Additionally this change contains fixes in load-forwarding that are needed to guarantee that all artificial LoadField instructions inserted during AllocationSinking are correctly replaced with actual values.

Limitations of the current implementation:

- can't eliminate allocations that flow into phis but otherwise don't actually escape;
- can't sink allocations out of loops;
- allocation with type arguments are not handled.

kmillikin@google.com 7e31a88a0a Initial support for polymorphic inlining. 
Consider each polymorphic variant separately for inlining in frequency
order.  Share inlined bodies for shared targets.

Insert an SSA redefinition of the receiver in each inlined variant to
prevent hoisting.  Hoisting code specialized to the receiver (e.g.,
direct access to internal fields of typed data arrays) out of the
inlined body is not safe.

kustermann@google.com 79a5d57ed1 Fixed bug in vm/benchmark_test.h 
The Benchmark objects were marked as 'const', but Benchmark::CreateIsolate
writes to 'Benchmark::isolate_'. This was not discovered so far, since GCC
places the global Benchmark objects into a read-write section.

It turns out that clang is able to create the const Benchmark objects at
compile time and puts them into a read-only section of the ELF file (it probably
inlines the constructor).
Thus, at runtime Benchmark::CreateIsolate tries to write to a read-only address
and crashes with a SEGV.

hausner@google.com 8e29370a1b BREAKING CHANGE: enforce part of directive 
For historical reasons, the VM is currently too lenient when parsing library parts. Files that get loaded through a 'part' directive must start with a 'part of libraryname;' clause. The VM so far has not reported an error if the clause is missing.

This change enforces the grammar as the Spec mandates it. Library parts that do not start with 'part of' will no longer compile.

A closure may be called from native code. In that case we will not
find a saved context variable in the dart frame 'below' the closure.

sgjesse@google.com 2fdb878ebe Change the signature for all network bind calls. 
All the bind calls on RawServerSocket, ServerSocket,
RawSecureServerSocket, SecureServerSocket and HttpServer (and
bindSecure on HttpServer) now have mandatory address and port
parameters. All the rest of the parameters are named optional
(including backlog).

The address parameter can be an InternetAddress or a String for all
these calls.
