6e30a77ab5 A number of instructions use GVN but do not provide a comparison 
function for the data. This leads to wrong results where operations
are wrongly assumed to have the same value as a previous (different)
operation.

Provide the data comparison functions.

BUG=995

1b67320800 Perform more aggressive time to NaN conversions. Our internal date 
methods rely on the time values passed in being within a certain range
- not significantly larger than the the ECMA 262 specified time
range. When creating a time, always make it NaN if there is no way
that it can be within range even after UTC conversion.

357afa385b Change Object.defineProperty to accept undefined as getters and setters and to correctly accept overriding an accessor with a data property. 
In the past we only accepted functions as argument for setting an
accessor. Since one should be able to set an accessor to undefined
this had to be changed to take either.

In addition, we did not lookup properties in the prototype chain,
causing us to call the setter of an existing accessor up the prototype
chain when trying to replace an existing accessor (that was not local)
with a data property.

ace6290452 Fix issue 974. 
When entering a finally block in unoptimized code, we unconditionally
save the accumulator register in the stack in case it holds a return
value or an exception.  In the case of a break, continue, or falling
off the end of the try or catch block, this value is unpredictable and
not necessarily safe for GC.

49f4c39d6d Deoptimize to the proper target after assignment side effects. 
This fixes V8 issue 989.

Before, assignments used the AST ID of the assignment expression to
mark the side effect of the store, which became a target for
deoptimization bailout for code after the assignment.  In effect
contexts this environment included the value of the assignment, which
was unexpected by the unoptimized code.

Now we introduce a new assignment ID for AST node types that include
an assignment (Assignment, CountOperation, and ForInStatement) and use
it for the side effect of the store.

SplitBetween (formely known as Split with 3 arguments) should select split position from [start, end] instead of [start, end[. This should also improve allocation quality (remove certain redundant move patterns).

e0d3f6afdf Be more careful about exiting inlined functions in a test context. 
When falling off the end of a function inlined in a test context, we cannot
constant fold the test of undefined away. The graph builder assumes that
control flow always reaches both branches of a test.

Instead, explicitly test and branch on "undefined". Introduce a pair of
empty blocks to hold the necessary LeaveInlined instructions.
