  [Clang] Remove 3-element vector load and store special handling

Clang uses a long-time special handling of the case where  3 element vector loads
and stores are performed as 4 element, and then a shufflevector is used to extract
the used elements. Odd sized vector codegen should now work reasonably well.

This patch removes this special handling, as well as the compiler argument
`-fpreserve-vec3-type`.
