Duncan P. N. Exon Smith 42f8eee150 cmath: Skip Libc for integral types in isinf, etc. 
For std::isinf, the standard requires effectively calling isinf as
double from Libc for integral types. But integral types are never
infinite; we don't need to call Libc to return false.

Also short-circuit other functions where Libc won't have interesting
answers: signbit, fpclassify, isfinite, isnan, and isnormal.

I added correctness tests for integral types since we're no longer
deferring to Libc.

In review it was pointed out that in future revisions of the C++
standard we may add more types to std::is_arithmetic (e.g.,
std::is_fixed_point).  I'll leave it to a future commit to hack this to
allow using math functions on those.  We'll need to change things like
__libcpp_fpclassify anyway, so I'm not sure anything here would really
be future-proof.

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!

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);
}
