Remove LowerAllocations pass.
Update some more passes to treate free calls just like they were treating FreeInst.

Update all analysis passes and transforms to treat free calls just like FreeInst.
Remove RaiseAllocations and all its tests since FreeInst no longer needs to be raised.

Remove AllocationInst.  Since MallocInst went away, AllocaInst is the only subclass of AllocationInst, so it no longer is necessary.

when the invoke had multiple return values: it set the lattice value only on the
extractvalue.
This caused the invoke's lattice value to remain the default (undefined), and
later propagated to extractvalue's operand, which incorrectly introduces
undefined behavior.

 - Some clients which used DOUT have moved to DEBUG. We are deprecating the
   "magic" DOUT behavior which avoided calling printing functions when the
   statement was disabled. In addition to being unnecessary magic, it had the
   downside of leaving code in -Asserts builds, and of hiding potentially
   unnecessary computations.

This adds location info for all llvm_unreachable calls (which is a macro now) in
