3c3d7e7be8 Revert "Removed support deprecated (//@|/*@) source(URL|MappingURL)=" 
A lot of deverlopers use deprecated sourceURL syntax. We should add console warning message before removing this.

322ffda30d [builtins] Migrate Number constructor similar to String constructor. 
Also migrate the Number constructor to a native builtin, using the
same mechanism already used by the String constructor. Otherwise just
parsing and compiling the Number constructor to optimized code already
eats 2ms on desktop for no good reason, and the resulting optimized
code is not even close to awesome.

Drive-by-fix: Use correct context for the [[Construct]] case of the
String constructor as well, and share some code with it.

065e9c536f [runtime] Migrate several Date builtins to C++. 
Almost all of the Date builtins always call into C++ at least once
anyway, so parsing, compiling and executing the JavaScript wrappers
is just a waste of time.  The most important part here is the Date
constructor itself, which is one of the blockers for new.target in
TurboFan, because compiling the Date constructor takes too much time
with TurboFan (for no reason since we end up in C++ anway).

372763897d Lazy call to custom stack trace formatting using Error.prepareStackTrace. 
This enables custom stack trace formatting for stack overflow.
A consequence is that stack trace formatting is now easily observable,
but we already established that the default stack trace formatting can
be observed anyways. It is only triggered by the .stack getter, and
it has to be explicitly called, (e.g. not implicitly after GC).

a3f16f8e65 Fix several bugs in error stack trace formatting. 
GetScriptWrapper can be called recursively:
GetScriptWrapper -> GC -> DeferredFormatStackTrace -> GetScriptWrapper

GC-unsafe code in ErrorObjectList::DeferredFormatStackTrace

Enable overwriting Error.prepareStackTrace by itself while not
causing infinity recursion when it triggers an exception.

118a2ccc8e When Error.collectStackTraces is set to true all new instances of 
Error, ReferenceError, etc. are given a stack property that gives a
stack trace.  Here's an example stack trace:

ReferenceError: FAIL is not defined
    at Constraint.execute (deltablue.js:527)
    at Constraint.recalculate (deltablue.js:426)
    at Planner.addPropagate (deltablue.js:703)
    at Constraint.satisfy (deltablue.js:186)
    at Planner.incrementalAdd (deltablue.js:593)
    at Constraint.addConstraint (deltablue.js:164)
    at Constraint.BinaryConstraint (deltablue.js:348)
    at Constraint.EqualityConstraint (deltablue.js:517)
    at chainTest (deltablue.js:809)
    at deltaBlue (deltablue.js:881)
    at deltablue.js:888

If Error.prepareStackTrace holds a function this function is used to
format the stack trace, for instance allowing code generators to
customize the way stack traces are reported to make them easier to
process.

Next step: performance measurements to see if it is feasible to turn
this on by default.
