History
Steven Perron f46f2d3e5d Remove redundant stores. 
The code patterns generated by DXC around function calls can cause many
store to be storing the same value that was just loaded from the same
location:

```
%10 = OpLoad %type %var
OpStore %var %10
```

We want to clean these up very early on because they can cause other
transformations to do a lot of work.  For the cases I see, they can be
removed during local-single-block-elim.

For one set of shaders the compile time goes from 248s to 182s.  A 26%
improvement.
