Error.stack contains function.name if its type is string.
Otherwise if function have inferred name then .stack contains it.
For functions from eval .stack property contains "eval".

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).

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.
