Add memory qualifiers (coherent volatile restrict) to imageSize(), imageLoad(),…

Add memory qualifiers (coherent volatile restrict) to imageSize(), imageLoad(), imageStore(), atomic*(), and imageAtomic*(), to remove errors about dropping qualifiers. Several bugs are related to this, and this is a slightly speculative fix, bit it is certainly wrong to either do it the way it was or to reflect the current specifications. git-svn-id: https://cvs.khronos.org/svn/repos/ogl/trunk/ecosystem/public/sdk/tools/glslang@28968 e7fa87d3-cd2b-0410-9028-fcbf551c1848
