- implemented vector operations. Vectors are now fully working as local variables.

- removed mulv_kr and divv_kr instructions. The first are redundant and the second are useless. Maybe remove all other vector/const operations as well? They won't get used by the code generator. - fixed disassembly of vector multiplication and division instructions.
