Log Message:
Introduced a Py_IS_NAN macro, which probably works on the major platforms
today.  pyconfig.h can override it if not, and can also override
Py_IS_INFINITY now.  Py_IS_NAN and Py_IS_INFINITY are overridden now
for Microsoft compilers, using efficient MS-specific spellings.

+- pyport.h now defines a Py_IS_NAN macro.  It works as-is when the
+  platform C computes true for ``x != x`` if and only if X is a NaN.
+  Other platforms can override the default definition with a platform-
+  specific spelling in that platform's pyconfig.h.  You can also override
+  pyport.h's default Py_IS_INFINITY definition now.
