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.

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).

615add8463 Expose APIs for detecting boxed primitives, native errors and Math.
While implementing structured clone I found that I need support
for detecting and creating objects using the builtin Number, String
and Boolean constructors; this CL adds this support. I also need
to be able to detect entities of "native object type (e.g., Error)",
hence the new IsNativeError() calls.

(ref: http://www.whatwg.org/specs/web-apps/current-work/multipage/urls.html#safe-passing-of-structured-data)

jsregexp.h is itself included transitively quite a lot, and by getting rid of 19
of its dependencies (which even included things like src/cpu.h, the various
assemblers, etc.), the recompilation behaviour is a bit less funny than it was.

10bb16f495 Add support for lazy deoptimization from deferred stack checks
The debugger can be entered from the deferred stack check in optimized code. This can cause both lazy deoptimization and debugger deoptimization (setting the first break point and inspecting the stack for optimized code respectively). This required deoptimization support from the deferred stack check.

The lazy deoptimiztion call is inserted when the deferred code is done including restoring the registers. The bailout to the full code is the begining of the loop body as that is where the stack check is sitting in the optimized code. The bailout is not to the stack check in the full code as that is sitting at the end of the loop.

57c29c1f29 Fix a bug in with and catch context allocation.
We were only looking one level up the scope chain to decide which
closure to use in the fresh context.  Instead, we should look to the
first non-catch scope.

9cc5b94c2e Correctly handle the constant pool in constant pool splitting test
The constant pool was not taken into account in the test test-compiler/SplitConstantsInFullCompiler which caused random failures.

This also reverts the test code added in r8469 and r8471.
