Fix alignment bug in Safe-Linking
Alignment checks should be performed on the user's buffer and NOT
on the mchunkptr as was done before. This caused bugs in 32 bit
versions, because: 2*sizeof(t) != MALLOC_ALIGNMENT.
As the tcache works on users' buffers it uses the aligned_OK()
check, and the rest work on mchunkptr and therefore check using
misaligned_chunk().
