Before inserting llvm.dbg.declare intrinsic at the end of a basic block, check whether the basic block has a terminator or not.
This API is used by clang and the test case is test/CodeGen/debug-info-crash.c in clang module. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94820 91177308-0d34-0410-b5e6-96231b3b80d8
