asiva@google.com 62115b51fe Fix for issue 7757 
- Iterate and collect all the inlined functions in an optimized dart frame
  into the stack frame when throwing an exception.
- Added a OptimizedDartFrameIterator class which iterates over all the inlined
  functions of a single optimized dart frame.

fschneider@google.com a42474ba37 Reland: Improve smi shift operations and avoid repeated deoptimizations. 
This CL includes a bug fix where a NULL check of the pc was missing.

Also change the dart2js test status of arithmetic_test from Skip to Fail.

fschneider@google.com 0f251088ec Improve smi shift operations and avoid repeated deoptimizations. 
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.

Added a test case for the code that was not covered by existing tests.

kmillikin@google.com 3d684dcc70 Compress deoptimization information by sharing common suffixes. 
For all the deoptimization entries in a function, build a suffix trie.  Add
a new deoptimization instruction that indicates the rest of the translation
is a fixed-length suffix of another entry.

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.

Put the PC (offset) of the deoptimization point and the deoptimization
reason in the DeoptInfo table.  The table entries are now triples of

srdjan@google.com a1cab6c167 Split deopt-after and deopt-before handling: 
- deopt-before describes a deoptimization that occurs before the instructionhas completed and requires a stub
- deopt-after describes deoptimziation after the instruction, used by lazy deooptimization, requires no stub.

vegorov@google.com a573d2dec8 Unbox phis that were proven to be of type Double. 
Eliminate Boxing/Unboxing pairs.

Allow boxing, unboxing and double binary operations to participate in CSE.

Allow double comparisons to operate on unboxed inputs.

Support XMM registers and double spill slots in deoptimization.

Save XMM registers when calling to runtime from WriteBarrier stub.
