compatible target triple Currently, an assertion fails in ThinLTOCodeGenerator::addModule when the target triple of the module being added doesn't match that of the one stored in TMBuilder. This patch relaxes the constraint and makes changes to allow target triples that only differ in their version numbers on Apple platforms, similarly to what r228999 did. rdar://problem/30133904 Differential Revision: https://reviews.llvm.org/D33291 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@303326 91177308-0d34-0410-b5e6-96231b3b80d8
