950ee77d24 [libcxx] Fix SFINAE in <cmath>. Patch from K-Ballo. 
Delay instantiation of `__numeric_type` within <cmath>, 
don't instantiate it when the `is_arithmetic` conditions do not hold as it causes
errors with user-defined types with ambiguous conversions. Fixes PR21083.

f4124610c2 Add return statement to slice_array and mask_array assignment. Closes PR20614. 
This patch just adds the required return statements to slice_array::operator=
and mask_array::operator=.

Tests were added to check that the return value is the same as the object assigned
to.

2af66e9851 Mark math.h and cmath tests as xfail on linux. 
These tests were marked as failing because the libc implementation does not
use the proper return type on certain math functions. There is other weirdness
that prevents us from defining our own version of these functions.

The failing tests in cmake were separated into their own files so that the rest
failures in the rest of the cmath tests were not hidden.

This was not done for the math.h test since we don't actually supply math.h

4d9f97b40b [libc++] Don't return uninitialized data from random_device::operator() 
Make sure we appropriately retry calls to read if the return result is
less than what we asked for.

Additionally, check and handle IO errors: EINTR results in the read
operation getting restarted; other errors turn into exceptions.

8db32cc2ac [libc++] random_device fails if open returns zero 
random_device::random_device(const string&) wrongly assumes that open
can only validly return a file descriptor greater than zero.

This results in random_device believing that it didn't successfully open
the device causing it to throw in it's constructor, this ends up leaking
a file descriptor.

The fix is simple, don't error on file descriptors which are zero.

bdfc0ad2ea Remove XFAIL from a number of tests that aren't expected to fail 
These tests haven't been failing on darwin11 or 12 since r189610 when
pr17027 was fixed, but they've been keeping the libc++ bot red by
XPASSing since then.

92a836c03d Reimplemented much of <istream> such that single character extractions do not check to see if this is the last character in the stream and thus never set eofbit. This fixes http://llvm.org/bugs/show_bug.cgi?id=10817 . This fix requires a recompiled libc++.dylib to be fully implemented. The recompiled libc++.dylib is ABI compatible with that shipped on Lion.

5430540d57 [rand.dist.samp.plinear]. This means we've got a fully tested and functional <random>! 489 tests over 48 sections are passing. :-) The only thing still on my plate in this area is to back-port some of this technology to random_shuffle/shuffle in <algorithm>. That will involve shuffling header bits around (<random> depepends on <algorithm>), but it won't entail that much development (compared to what has been required for <random>).
