Condition to use for a `MUX` instruction. `neg` checks the sign bit,
`int_zero` compares to `0x00000000`, `fp_zero` compares to $\pm 0.0$ as
an IEEE 754 float, and `bit` checks each bit separately. The `bit` mode
acts like an imaginary `CSEL.v32i1` instruction, and implements
acts like an imaginary `CSEL.v32u1` instruction, and implements
`bitselect()` in OpenCL.
