[PATCH] [TargetLibraryInfo] Update run time support for Windows
It seems that the run time for Windows has changed and supports more math
functions than before. Since LLVM requires at least VS2015, I assume that
this is the run time that would be redistributed with programs built with
Clang. Thus, I based this update on the header file `math.h` that
accompanies it.
This patch addresses the PR40541. Unfortunately, I have no access to a
Windows development environment to validate it.
