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.

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.

fschneider@google.com 253c3f8499 Implement class id checks as a separate instruction and add a local CSE optimization pass. 
This CL contains:
A new CheckClassComp instruction. Currently it is used only for instance loads:
(LoadInstanceFieldComp)

A pass LocalCSE that performs block-local common subexpression elimination. To identify
redundant expressions I use a hash map per basic block. Computations that do not have
side effects can participate in CSE. For now, I only enabled it for CheckClass.
Any computation that participates in CSE must implement the AttributesEqual function.


Other smaller fixes:

Places where we can pass the correct initial size for GrowableArrays
that have a known size. We should consider having a FixedLengthArray for this purpose.

Made the accessors ic_data() and set_ic_data() use a const ICData*.

srdjan@google.com ac8041f15d First step toward deoptimization using deoptimization info: splits deoptimization into two steps: copy frame to buffer, fill unoptimized frame from buffer. The only changes in the frame are the return address and the PC marker. 
Second step will add deoptimization info 'instructions' that will fill the unoptimized frames using the saved registers and frame data.

vegorov@google.com c9e8d9594e Add support for fixed parameters in the register allocator. 
This remove bailout for functions with non-zero number of non-fixed parameters and increases our coverage.

SpillSlot location was renamed into StackSlot location and now allows to address spill slots (positive stack index) and incoming parameters (negative stack index).

Environment was reordered to match order of values on the stack (previously it was inversed).

Correctly reserve spill slots in the prologue of the code. Previously register allocator was allocating spill slots, but generated code did not reserve any space for them on the stack so they might have been overwritten by calls.

Fix off by one in DeoptimizationStub::GenerateCode - we were reserving one slot too many.

Change --optimization-filter flag to use substring search instead of prefix comparison, this is much more useful when VM prefixes function name with a path to the file.

- Avoids the need for doing a NewSymbol on these everytime
- saves space as they get shared by isolates
