AIX's system header provides these C++ overloads for compatibility with older XL C++ implementations, but they can be disabled by defining __LIBC_NO_CPP_MATH_OVERLOADS__ since AIX 7.2 TL 5 SP 3. Since D109078 landed clang will define this macro when using libc++ on AIX and we already run the lit tests with it too. This change will enable the overloads in libc++'s math.h and we'll continue to require the compiler to define the macro going forward.
