As discussed on PR27654, this patch fixes the triples of a lot of aarch64 tests and enables lit tests on windows This will hopefully help stop cases where windows developers break the aarch64 target Differential Revision: https://reviews.llvm.org/D22191 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@275973 91177308-0d34-0410-b5e6-96231b3b80d8
