[Sema] Make extended vectors of `bool` an error. In OpenCL, `bool` vectors are a reserved type, and are therefore illegal. Outside of OpenCL, if we try to make an extended vector of N `bool`s, Clang will lower it to an `[N x i1]`. LLVM has no ABI for bitvectors, so lots of operations on such vectors are thoroughly broken. As a result, this patch makes them illegal in everything else, as well. :) Differential Revision: http://reviews.llvm.org/D15721 llvm-svn: 259011 2016-01-28 09:38:18 +08:00			`// RUN: %clang_cc1 %s -verify -pedantic -fsyntax-only`
