Instead now use HasInstance() to verify that the object is a Buffer, and throw if not. This check will not work for JS only methods. So while the application won't abort, it also won't throw. In order to properly throw in all cases with toString() the JS optimization of checking that length is zero has been removed. In its place the native methods will now return early if a zero length string is detected.

buffer: prevent abort on bad proto

If an object's prototype is munged it's possible to bypass the
instanceof check and cause the application to abort. Instead now use
HasInstance() to verify that the object is a Buffer, and throw if not.

This check will not work for JS only methods. So while the application
won't abort, it also won't throw.

In order to properly throw in all cases with toString() the JS
optimization of checking that length is zero has been removed. In its
place the native methods will now return early if a zero length string
is detected.
