David Greene 127fd1d540 [AVX] Add type checking support for vector/subvector type constraints. ...

This will be used to check patterns referencing a forthcoming
INSERT_SUBVECTOR SDNode.  INSERT_SUBVECTOR in turn is very useful for
matching to VINSERTF128 instructions and complements the already
existing EXTRACT_SUBVECTOR SDNode.
