My change 28205b203a4742c40080b4a2b4b2dcd800716edc added -fno-strict-aliasing on clang to fix the compilation of Python/dtoa.c on clang 4.0. But it's only a temporary workaround until dtoa.c is fixed to respect C99 strict aliasing.

Strict aliasing allows the compiler to enable more optimization, and so should make Python a little bit faster. It would only fix a regression, before my change Python was already build with strict aliasing
