Reapply a fixed version of r133285. · 3c68b626

Bob Wilson authored Jul 08, 2011

This tightens up checking for overflow in alloca sizes, based on feedback
from Duncan and John about the change in r132926.

- LICM: Do not loose alignment on promotion · 4a5d9a9c
  Tobias Grosser authored Jul 06, 2011
```
The promotion code lost any alignment information, when hoisting loads and
stores out of the loop. This lead to incorrect aligned memory accesses. We now
use the largest alignment we can prove to be correct.

PR10267: Don't combine an equality compare with an AND into an inequality compare when the AND has more than one use.

This can pessimize code, inequalities are generally more expensive.

Generalize @llvm.ctlz, @llvm.cttz, and @llvm.ctpop to work on vectors of integers, and fix the one optimization pass that I'm aware of that needs updating for this.  At least one current target, ARM NEON, can implement these operations on vectors directly.
