Update the macro that MSVC 2013 defines for AVX code generation

http://msdn.microsoft.com/en-us/library/b0084kay(v=vs.120).aspx says:
  __AVX__       Defined when /arch:AVX is specified.

Now we know what flag it is, we don't need to use our _M_AVX flag
anymore. We're also now assuming that Microsoft will follow the same
pattern for AVX2 (i.e., __AVX2__), so this commit also removes the
check for _M_AVX2.

The other defines that were defined alongside AVX2 are removed because
they have no use currently in Qt.
