Ulrich Weigand e07464832d [SystemZ] Mark v1i128 and v1f128 as unsupported

The ABI specifies that <1 x i128> and <1 x fp128> are supposed to be
passed in vector registers.  We do not yet support those types, and
some infrastructure is missing before we can do so.

In order to prevent accidentally generating code violating the ABI,
this patch adds checks to detect those types and error out if user
code attempts to use them.
