StackPRE

```
public class StackPRE
extends java.lang.Object
```
Eliminate partially redundant local variable loads and stores by replacing them with stack variables and dups. The algorithm is similar to SSAPRE, except: We need to place phis for locals at the IDF of the blocks containing defs and uses (not just defs).
