Break dependency on byteswap.h
Summary:
Unfortunately, this doesn't exist on all platforms. Fortunately, both
gcc and clang support builtins that do the same thing as the bswap_*
functions we were including byteswap.h for.
I changed the test file to hardcode expected results for the swapping
functions. Is that OK? It seemed a little silly to be testing the
Endian::whatever functions by comparing them against the functions that
they're implemented in terms of.
Test Plan:
fbconfig/fbmake runtests with gcc 4.6 and 4.7. Verified
separately that clang supports these builtins.
