Reads and write syntax to UAV objects is turned into EOpImageLoad/Store operations. This translation did not support destination swizzles, for example, "mybuffer[tc].zyx = 3;", so such statements would fail to compile. Now they work. Parial updates are explicitly prohibited. New test: hlsl.rw.swizzle.frag
