Browse source 
Basically identical to MUX.i32, slight differences in opcode and swizzling only.

<desc>
Mux between A and B based on the provided mask. The condition specified
as the `mux` modifier is evaluated on the mask. If true, `A` is chosen,
else `B` is chosen. The `bit` modifier acts bitwise, equivalent to
`bitselect()` in OpenCL, so `MUX.i32.bit A, B, mask` calculates
`(A &amp; mask) | (A &amp; ~mask)`.
