to handle LLVMMatchType intrinsic parameters, and by adding new subclasses of LLVMMatchType to match vector types with integral elements that are either twice as wide or half as wide as the elements of the matched type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61834 91177308-0d34-0410-b5e6-96231b3b80d8
