asiva@google.com f4fe42c280 Added macros OBJECT_IMPLEMENTATION and FINAL_OBJECT_IMPLEMENTATION 
which have different implementations of 'operator=' and 'operator^='.
In the case of FINAL_OBJECT_IMPLEMENTATION we do not do the vtable setting
in these methods (Note the |= operator functionality is now subsumed into
the new implementation of "operator^=")

kmillikin@google.com 8c4e214722 Pass IC data and arguments descriptor to IC miss runtime functions. 
Before, we obtained them by pattern matching backwards on the machine
instructions at the call site.  This previous approach becomes unwieldy when
we need to use to use multiple instance call patterns.

Smi left shifts do not contain a call now. Only after deoptimizing
at a smi operation we we generate mint code or a generic call to
avoid repeated deoptimization.

srdjan@google.com 64a5b5f609 In optimized code always deoptimize if we encounter an instance call without type feedback (ICData has no checks). 
Fix a bug in inliner: do not inline methods that have no compiled code as we can not deoptimize into them. This is the simplest fix, more complex fixes can be implemented if we see a need for them.

This improves the speed of Meteor by 15% and NavierStokes by 40% (Mac OS X).

fschneider@google.com 6632f191c4 Support for unboxed 64-bit integer bitwise operations and equality on ia32. 
This CL adds AND, OR, XOR and == operations on unboxed 64-bit integers
(aka. mints).

Unboxed mints are stored in xmm registers. Each xmm register location
has an additional bit to keep track of its value representation.

Unboxed mints are materialized on the heap on deoptmization in the same way as
unboxed doubles.

The SSE instructions used are available on all CPUs that support SSE 4.1.

srdjan@google.com caf04303f7 Deoptimization can occur at Dart calls (includes native calls to C) but not at runtime calls. This assumption (verified with Todd and Gilad) simplifies the implementation of lazy deoptimization considerably. 
Add flag --deoptimize-alot, which will lazily deoptimize all live optimized frames. Currently only the presence of deoptimization information is checked.

Add kDeoptAfter deoptimization point, which is the continuation for lazy deoptimization, after a call. Rename kDeopt to kDeoptBefore.

Removed a tests case that called into a native without properly setting up a Dart frame (Ok-d by Siva).

Native functions are not optimizable.

TODO: Split deoptimization information from DeoptimizationStubs. Check for redundant PcDescriptor information (what can be merged, especially at calls).
