jgruber be5808bff8 Correctly format builtin constructors in stack traces
CallSite::IsConstructor() was unable to recognize builtin construct stubs
(NumberConstructor_ConstructStub and StringConstructor_ConstructStub) as
constructors, and thus these frames were not formatted correctly in stack
traces.

Fix this by explicitly marking their Code objects as construct stubs and
passing along a special receiver value when we encounter such cases in
CaptureSimpleStackTrace.
