Inconsistent stackmap frames for TwoWord arguments

[marchof]

Inserted frames are incorrect in the following situation:

• At least one method argument is TwoWord (long or double)
• A stackmap frame does not contain these arguments as local variables (not used any more).

These situations do not occure with the Java compiler, but with certain tools. See issue jacoco/eclemma#46

In this case the number of Top elements which need so be inserted before the probe variable is too small as the TwoWord size is not properly considered.

Apologies for the delay in testing this, I've been on hols.

The latest snapshot fixes the problems I had, both in the small test project and the original library where I encountered it. Thanks for the quick fix Marchof. Looking forward to the 0.6.3 release.
