John Stiles 28054added Optimize ternary tests that check a const variable. 
This enables the ternary to be optimized away in code like:
   const bool SHINY = true;
   color = SHINY ? add_shine(x) : x; // to --> `color = add_shine(x);`

Without constant propagation.

Also, I added a unit test for ternary expression simplification; I
wasn't able to find an existing one.

When the optimization flag is disabled, this CL actually removes the
optimization of `true ? x : y` --> `x` entirely; previously, this
substitution would be made regardless of optimization settings.
