Exception filtering is not yet supported.

For an example of Exception filtering in C# see http://pastebin.com/URkYjsiE

Note from #64 (see also https://github.com/CosmosOS/IL2CPU/pull/64#discussion_r223853431): When throwing an exception, we should empty the stack (if there's no item in the stack, do nothing). I think it would be a good idea to add some common infrastructure to throw exceptions.

It would also be helpful if exceptions in using blocks are also supported. As they right now lead to crashes (CPU Exception 6). Example code: https://github.com/CosmosOS/Cosmos/blob/8b7613e2d81b004e4af72210a7afa60895818231/Tests/Kernels/Cosmos.Compiler.Tests.Exceptions/Kernel.cs#L167
