Hexagon (target/hexagon) cleanup ternary operators in semantics 

Change  (cond ? (res = x) : (res = y)) to res = (cond ? x : y)

This makes the semnatics easier to for idef-parser to deal with

The following instructions are impacted
    C2_any8
    C2_all8
    C2_mux
    C2_muxii
    C2_muxir
    C2_muxri
