Add a constructor for BuildVectorSDNode and revert the temporary workaround

from 66280.  I was unable to verify this with gcc-3.4.6, but with gcc-3.3 it
avoids the "base class with only non-default constructor in class without
a constructor" warning.  Apparently that warning was promoted to an error
in gcc-3.4.
