        <pre>This failure is a representative example for Mips:
    libc++ :: std/utilities/tuple/tuple.tuple/tuple.elem/get_const_rv.fail.cpp

One workaround seems to be adding -fintegrated-as but there's presumably a bug
in clang that this leaves unaddressed.

In addition, when I tried -save-temps, the verifier failed to find error
messages due to line wrapping caused by long paths. For example:
/scratch/mipssw1erpro002/das-local/llvm-3.8/release/rc1/libcxx.src/test/std/utilities/tuple/tuple.tuple/tuple.elem/get_const_rv.fail.cpp:32:9:
error: 
      call to deleted function 'cref'
        cref(std::get<0>(tup4()));  // expected-error {{call to deleted
function 'cref'}}
        ^~~~
<snip>
error: 'error' diagnostics expected but not seen:
  File
/scratch/mipssw1erpro002/das-local/llvm-3.8/release/rc1/libcxx.src/test/std/utilities/tuple/tuple.tuple/tuple.elem/get_const_rv.fail.cpp
Line 32: call to deleted function 'cref'

With a shorter filename, both parts appear on the same line and the verifier
doesn't report failure.</pre>
