Fix issues with JSON stringify replacer array

If the replacer array contains a property key we should include the
property even if the property is non enumerable or if it is a non own
property.

String and Number wrappers in the replacer array should be treated as
string and number values.

Fix VPrintHelper used on Windows.

VPrintHelper would silently ignore the stream given to it if application is in GUI mode (no console is attached) and redirect output to the debugger via OutputDebugString.

Such redirection makes sense only if passed stream is either stderr or stdout. Don't redirect any other stream to the debugger.

Reorder clauses in VPrintHelper to make condition more readable.

Bugfix for 349874: we incorrectly believe we saw a growing store

When we set an out of bounds array index, the index might be so large that
it causes the array to go to dictionary mode. It's better to avoid
"learning" that this was a growing store in that case.

This fix also partially reverts a fix for bug 347543, as this fix is
comprehensive and satisfies that repro case as well (partial revert of
v19591).
