Perform and context frame size primitive tests

Yes, this is one thing, which i discovered during NativeBoost development.

I made the patch which fixes it
http://code.google.com/p/nativeboost/downloads/detail?name=001-perform-framesize.cs

Note that it deals with #perform:withArguments:
but not with #perform:withArguments:inSuperclass:

means that if you use the #perform:withArguments:inSuperclass: , it
also may fail, depending on call site, which may not fit all arguments
into
context stack. See senders of it.

The main reason why it works on Cog i think, that Cog maps contexts to
stack.. so contexts don't have  a hardcoded limits of their stack
sizes.
(but that juts guess , i didn't checked it)
