Many Linux targets duplicate the cpp spec macros for turning -posix/-thread

std::equal((int*)0, (int*)0, p) and std::equal(p, p, (int*)0) are
valid for any input iterator p, and must not pass a null pointer to

The following patch fixes loop vectorization of SLP reduction chains

This patch avoids the use of the secondary stack, and the corresponding cleanup

Hi,
here is updated version of patch. It makes alias_set_subset_of to be symmetric
