Tell the compiler that QArrayData returns aligned pointers
GCC 4.9 and later support the __attribute__((alloc_align)) attributes
that indicate the alignment of the data. To make it work on GCC since
4.7 and Clang as of 3.6, we instead use __builtin_assume_aligned(). I
don't know which version of ICC first implemented this, but ICC 15 does
and it also reports itself as GCC 4.9.
