Detailed Description

ExtVectorElementExpr - This represents access to specific elements of a vector, and may occur on the left hand side or right hand side. For example the following is legal: "V.xy = V.zw" if V is a 4 element extended vector.

Note that the base may have either vector or pointer to vector type, just like a struct field reference.
