Peter Collingbourne 6b5c08ab34 libcxx: Move #include_next <math.h> out of header guard in wrapper header.
Code on Windows expects to be able to do:

 #define _USE_MATH_DEFINES
 #include <math.h>

and receive the definitions of mathematical constants, even if <math.h>
has previously been included. To support this scenario, re-include
<math.h> every time the wrapper header is included.
