Looks like this test is failing on SystemZ since it was added, making all our
build bots red:
/home/uweigand/sandbox/buildbot/clang-s390x-linux/llvm/tools/clang/test/CodeGenCXX/builtin_FUNCTION.cpp:9:11:
error: CHECK: expected string not found in input
// CHECK: @[[EMPTY_STR:.+]] = private unnamed_addr constant [1 x i8]
zeroinitializer, align 1

@.str = private unnamed_addr constant [1 x i8] zeroinitializer, align 2

The problem is that string constants are 2-aligned according to the SystemZ ABI
(this is a bit different, but deliberate in order to allow computing their
addresses with a LARL instruction). This makes all the "align 1" checks fail.
Is this test deliberately verifying the alignment, or could this just be
removed?
