f17bd8ca51 Fix three bugs with handling negative zero in the optimizing compiler.
* Bug fix for range analysis (contributed by Andy Wingo). Ranges of
double values have to include negative zero. Original code review:
 http://codereview.chromium.org/7514040/

* Fix a bug in optimized Math.round on ARM. When emitting minus-zero checks
we previously return a wrong result because of incorrect register assignment.

* Fix performance problem in IA32 and x64. Refine the checks
for minus zero and avoid unnecessary deoptimizations on Math.floor.

* Improve mjsunit test for Math.round to make sure we also
 get the optimized version of the code for each test case.

caf493afb3 Make d8-os test less flaky.
Because of stress testing there may be parallel instances of the test
running, which makes it fail when using a hardcoded test dir
name. Adding a random suffix helps. It'd be nicer to add something
like pid, but there doesn't seem to be an easy way of getting it.

b625ce2b6b Fix a bug in scope analysis.
When recompiling code (e.g., when optimizing) we could incorrectly hoist
some function expressions.  This leads to incorrect results or a crash.  The
root cause was that functions were not correctly categorized as expression
or declaration at parse time.

This requires some extra hoops to prevent the print name "anonymous" for
functions created by 'new Function' from establishing a binding.

9721eddc1f Ensure that the length property of bound functions are actual unique
for the individually bound functions.

Our existing code will generate a new function on every call to bind,
but it will use the same shared function. When setting the lenght this
will be set on the shared function, i.e., the length of all bound
functions will be that of the last bound function.

bdf6895bb3 Encapsulate element handling into a class keyed on ElementsKind
Advantage is that it's much easier to add new element types (like FAST_SMI_ELEMENTS), and that handling logic for each element kind is (more) consolidated.

Currently, only GetElementsWithReceiver uses the new encapsulation, but the goal is to move much more element functionality into the class incrementally.

ffa08197e4 tighten invariants of HValue::InferRange
* src/hydrogen-instructions.cc (HValue::InferRange): Only mark values
  with int32 representation as never being -0.  Always return a non-NULL
  value; callers should check for representation().IsNone() if that's
  their concern.

  In practice these invariants were not violated by callers, but they
  were sometimes two calls away, which seems brittle.

4487f8c050 Revert "Revert "Fix a bug in scope analysis.""
Reapply r8783 with an additional fix.

Because the preparser and parser do not use the same scope analysis to
determine if a function can be lazily compiled, the parser can have false
positives.  Rather than treating this as a parse error, treat the preparser
as authoritative and eagerly compile the function.
