Comment out an assert which is giving bogus failures. On platforms where it isn't possible to detect NaN or infinity the full hash computation is performed on them. For NaN the result doesn't matter (since NaN != NaN), for infinity it should always give the same result), so the calculation works but unfortuanately, I don't know how to correctly check that v is what I expect in the assertion.
...
I could use a different hash function when I don't have fpclassify/fpclass but that shouldn't be necessary.

Use _fpclass and fpclassify on less platforms. Hopefully will use them more widely after the release.

In hash_float, only use _fpclass on Visual C++, I'll find out about other compilers later.

Make hash_float.hpp use its own combine function. This serves two purposes:
...
1. hash_float is no longer dependent on the main hash header.
2. hash_float(0) == 0 which makes it easier to implement hash<complex>(),
although this might lead to users assuming that it can be expected even though
it isn't part of the documented interface.
