  Log Message:
  -----------
  [SystemZ] Use the EVT version of getVectorVT() in combineTruncateExtract(). (#100150)

A test case showed up where the new vector type is v24i16, which is not a simple
MVT. In order to get an extended value type for cases like this, EVT::getVectorVT()
needs to be called instead of MVT::getVectorVT(), otherwise the following call
to getVectorElementType() in combineExtract() will fail.

(cherry picked from commit 22bc9db92b46965882b1c77aebc86430149b0912)
