6893cd7615 Make instcombine ensure that all allocas are explicitly aligned at at
least their preferred alignment.

0f2831c820 ValueTracker can't assume that an alloca with no specified alignment
will get its preferred alignment.  It has to be careful and cautiously assume
it will just get the ABI alignment.  This prevents instcombine from rounding
up the alignment of a load/store without adjusting the alignment of the alloca.
