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.

Harmony is intended to make typeof null === "null". This may

Because these are function literals that have an associated name, we were

Reapply r8838 with a fix for the issue of function names.

Because function names can be added/changed/removed through the API,
remember whether the function is anonymous when initially parsed and use

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.

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.

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.

Now that all natives functions are recognized as such, many of them
are called with undefined as the receiver. We have to use different
filtering for builtins functions when printing stack traces.

Also, fixed one call of CALL_NON_FUNCTION to be correctly marked as a
method call (with fixed receiver). Now that CALL_NON_FUNCTION is
marked as a native function this caused the receiver to be undefined.

6098abf46e Fix the debugger for strict-mode functions.
undefined is passed unchanged as the receiver for strict-mode
functions through call and apply. Also, if a strict-mode function is
called without an explicit receiver, undefined is passed as the
receiver (not the global object as for other functions).

The catch variable is bound in the catch scope.  For simplicity in this
initial implementation, it is always allocated even if unused and always
allocated to a catch context even if it doesn't escape.  The presence of
catch is no longer treated as a with.

In this change, care must be taken to distinguish between the scope where a
var declaration is hoisted to and the scope where the initialization occurs.

7d2be7c0e0 Support debugger inspection of locals in optimized frames
Optimized frames are now handled by the debugger. When discovering optimized frames during stack inspection in the debugger they are "deoptimized" using the normal deoptimization code and the deoptimizer output information is used to provide frame information to the debugger.

Before this change the debugger reported each optimized frame as one frame no matter the number of inlined functuions that might have been called inside of it. Also all locals where reported as undefined. Locals can still be reposted as undefined when their value is not "known" by the optimized frame.

As the structures used to calculate the output frames when deoptimizing are not GC safe the information for the debugger is copied to another structure (DeoptimizedFrameInfo) which is registered with the global deoptimizer data and processed during GC.

480ec43c4e Make "native" not a keyword.
We now only recognize "native function" when it occurs in extension scripts
(parsing with a non-NULL extension), and only if there is no line-terminator
between "native" and "function" (so that it would otherwise be a Syntax Error).
Preparsing never recognizes native functions, which is acceptable since we
never preparse extension scripts (because we don't allow lazy functions
anyway).

c95ecb1fcd Refix issue 1472. The previous fix worked for the example in the bug
report, but was not general enough to catch all cases.  This is a new
approach.  Includes regression test!

This avoids attempting to redefine function.arguments with a different
value than the current one. function.arguments returns a new copy on
each invocation.

The encoding constraint is that we have 128 values. We use [-64,0] for
parameters and [0,63] for locals. However, for locals we restricted to
64 and not 63.
