827e827b38 Cache result of ScriptNameOrSourceURL function. The function is quite slow on large(several MBs) scripts which causes significant slowdown when capturing stack trace for such scripts.

1336b913d0 Make built-ins strict mode conforming, and support a --use-strict flag. 
* Turned all uses of 'const' into 'var'.
* Turned all uses of local 'function' into 'var'.
* Added a couple of missing toplevel 'var' declarations.

One consequence is that the properties on the builtin object  are no longer
non-writable, and I had to adapt one test. Is that a problem?

Unfortunately, we cannot actually switch the library scripts to strict mode
by default, because that makes observable things like poisoned .caller properties
for library functions.

Also removed dead flag code in Compiler::Compile.

08b4262512 Statically check for assignments to const in harmony mode. 
The ES.next draft rev 4 in section 11.13 reads:
It is a Syntax Error if the AssignmentExpression is contained in extended code
and the LeftHandSideExpression is an Identifier that does not statically resolve
to a declarative environment record binding or if the resolved binding is an
immutable binding.

This CL adds corresponding static checks for the immutable binding case.

e26093f3d8 Make let/const outside of the extended mode early errors (under harmony flag). 
The ES.next drafts require that source code that matches the productions for
let and const bindings outside the extended mode trigger early syntax
errors. This CL adapts the parser / preparser accordingly under the harmony
scoping flag.

Summary:
* Harmony scoping flag not set: Old semantics allowing const in classic mode
with function level scope. Const binding in strict mode and let bindings in
classic and strict mode trigger early syntax errors.
* Harmony scoping is set: Use new harmony const and let in
extended mode and old const in classic mode. This is to preserve
compatibility with current web pages that already use
non-standard implementations of const. An early syntax error is
thrown on const in strict mode and on let in classic and strict
mode.

This depends on:

e8bccc2cb0 Block scoped const variables. 
This implements block scoped 'const' declared variables in harmony mode. They
have a temporal dead zone semantics similar to 'let' bindings, i.e. accessing
uninitialized 'const' bindings in throws a ReferenceError.

As for 'let' bindings, the semantics of 'const' bindings in global scope is not
correctly implemented yet. Furthermore assignments to 'const's are silently
ignored. Another CL will introduce treatment of those assignments as early
errors.

85f5afb717 Correctly mark functions from our natives files during compilation. 
When creating a CompilationInfo we always have the script and can
determine if it is a natives script.

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.

2b730c2bf6 Don't exchange null and undefined with the global object in function.prototype.{call, apply} for natives. 
This makes us compatible with firefox in throwing an exception when
call is invoked on a builtin with null as the this argument.

c6e37c5dfb Make Script.prototype.nameOrSourceURL use indexOf search first before trying to match with a RegExp. 
This should use Boyer-Moore search with a long string, which is potentially
faster than RegExp search.
The target string is typically, but not guaranteed, at the end of the
source, so for long sources, there will be a lot of characters to skip.

ReferenceError.prototype.__proto__ which will make "error instanceof
Error" fail. However, the ReferenceError.prototype object itself
cannot be modified. Therefore, the error checks must check for
concrete error instances instead of only checking for Error.
