Adds the "Vector Bit Manipulation Instructions 2" instruction set. These new instructions are added via the `opcodesextra` mechanism #345, since they're missing from the opcodes database. Contributed by @vsivsi. Extracted from #349 with simplifications. Specifically, as prompted by the `dupl` linter we extract some common forms lists into a helper `forms.go` file.
