Add a new factory method to `IncrementInstruction` that allows the explicit creation of a wide iinc instruction, even with a `slot` and `constant` that could fit into a normal iinc instruction. Previously, only one factory for iinc instructions existed, which inferred the type of instruction needed given the size of `slot` and `constant`. Add additional test cases for the new factory as well. All tier 1 tests and classfile tests have passed with these changes.
