panfrost/midgard: Map more bany/ball opcodes

Browse Source 
Some of these are not yet fully functional due to related bugs, but this
the correct op mapping. The native ball/bany opcodes act on vec4's
unconditionally. That said, both ball and bany have the nice property
that duplicating an argument does not affect their output, so the
default "hanging swizzles" allow us to implement 2/3-component opcodes
correctly, implicitly lowering.
