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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236526 91177308-0d34-0410-b5e6-96231b3b80d8
