baeddde44d DO NOT MERGE: [libc++] Add __truncating_cast for safely casting float types to integers 
This is needed anytime we need to clamp an arbitrary floating point
value to an integer type.

Thanks to Eric Fiselier for the patch.

1eab168286 math: add type promoting template definition on MSVCRT 
When building with MSVCRT, we need to manually provide the type
promoting overloads to allow the correct type deduced invocation for
signbit(Int) and fpclassify(int).

766ba68107 math: actually pull the declarations/overloads into std 
The previous changes missed the change to include/cmath.  These changes
allow some of the rand.distribution tests to pass on Windows.

bacb35f5ae math: follow up to SVN r294902 
Pull in the math functions from ucrt 14+ after auditing the library.  It
seems that they are now complete for C99 math.  Fixes more windows
tests!

be3d93ca48 math: pull more C functions from std 
The newer ucrt version provides the gamma meth routines.  Includede them
when building the library.

7666130d06 Fully qualify (preprend ::) calls to math functions from libc 
Summary:
This can cause a compile failure in cases like:

double log(double);
namespace foo {
  namespace log {}
}
using namespace foo;
void bar(int i) {
  log((double)i);
}

7dc2fa31af [libc++] Remove math_win32.h 
Visual Studio 2013 and onward have all the required functions in their
CRT headers, and we don't support older versions anymore.
