The original implementation of 'testAsync' in mjsunit.js required to
put the call to '%AbortJS' into an 'eval' statement. The reason is that
this call requires the flag --allow-natives-syntax to be set, but the
flag is not set in all mjsunit tests. With the use of 'eval'
compilation errors can be avoided.
The problem with this approach was that the fuzzer started to produce
test cases which include the line 'eval("%AbortJS(message)");', and
this line crashes intentionally. Different to the line
'%Abort(message)', however, the 'eval' statement cannot be filtered
so easily in the fuzzer. Therefore I pulled the implementation of
'testAsync' into a separate file to avoid the 'eval'.
Additional changes: I use '===' now instead of 'deepEquals' in
AsyncAssertion.equals because 'deepEquals' is not available outside
mjsunit.js. Using '===' seems more appropriate anyways because for
all tests but one it is sufficient, and it is more precise than
deepEquals.

Private fields should not return undefined on access miss, but instead
should throw a TypeError.
This patch uses a bit on v8::Symbol to mark if this symbol is a
private field or not.
This patch also changes the LookupIterator code path that deals with
LookupIterator::State::DATA to deal with JSReceiver instead of
JSObject.
Note: the error message doesn't output the field name, but that's a
WIP.
