OP_TYPE_CONVERTS denotes an opcode that returns a different type than is source (going from int-domain to float-domain or vice versa), named after the f2i/i2f family of opcodes it covers. We care because source mods are determined by the source type (i/f) but output modifiers are determined by the output type (equals the source type, unless the op type converts, in which case it's the opposite). The upshot is that floating-point compares (feq/fne/etc) actually do type-convert. That is, that take in floating-points and output in integer space (a boolean), so we mark them off this way to ensure the correct output modifiers are used.
