Index constant buffer vec4s using ternary expressions. (#1015)

Browse source 
* Index constant buffer vec4s using ternary expressions.

* Remove indexed path.

We determined that it had negligible impact.

* Revert "Remove indexed path."

This reverts commit 25ec4eddfa441e802bd957dfaabc83b23c6bae38.

* Revert "Revert "Remove indexed path.""

This reverts commit 7cd52fecb529dcb9e1a574533bd38531319f1268.
