Shoaib Meenai 17af695f2b [libc++] Drop support for CRTs older than VS 2015 
LLVM dropped support for Visual Studio versions older than 2015 quite
some time ago, so I consider it safe to drop libc++'s support for older
CRTs. The CRT in Visual Studio 2015 provides a lot of previously missing
functions, so targeting it requires less special casing.

Saleem Abdulrasool af14a631d0 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).

Saleem Abdulrasool 8a5789ebd1 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.

Saleem Abdulrasool ce5ce02604 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!

Saleem Abdulrasool 2fe5658d9a math: pull more C functions from std 
The newer ucrt version provides the gamma meth routines.  Includede them
when building the library.

Mehdi Amini 48b4b04700 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);
}

Shoaib Meenai 4e14445e59 [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.
