panfrost/midgard: Note floating compares type convert

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.
