Complete log of test run

The libc++ r153859 tests in numerics/rand, when compiled with clang r153864,
result in one failed assertion and four compilation failures (full log
attached):

[...]
Assertion failed: (p[0] == 1), function main, file ctor_default.pass.cpp, line
28.
./../testit: line 61: 70200 Abort trap              ./$TEST_EXE
/Users/rynnsauer/LLVM/libcxx/test/numerics/rand/rand.dis/rand.dist.samp/rand.dist.samp.discrete/ctor_default.pass.cpp
failed at run time

[...]

ctor_init_func.pass.cpp:33:11: error: no matching constructor for
initialization of 'D' (aka
      'piecewise_constant_distribution<>')
        D d({}, f);
          ^ ~~~~~
/usr/include/c++/v1/random:6016:9: note: candidate constructor [with
_UnaryOperation = double
      (*)(double)] not viable: cannot convert initializer list argument to
      'initializer_list<result_type>'
        piecewise_constant_distribution(initializer_list<result_type> __bl,
        ^

[...]

[three more similar bugs related to the use of initializer_list]

(the initializer_list bugs are possibly due to a bug in clang)
