Avoid creating 'load X, 0' instead of just 'load X'
...
This _trivial_ change causes GCSE and LICM to be much more effective at
hoisting loads. Before it would not be able to eliminate 'load X' if there
was just a dominating 'load X, 0' because the expressions were not identical.

- Add a new NewCasts member to VMC to keep track of casts that have been
created and to ensure there is always a reference to the cast.
- Extend ValueHandle a bit so it can be used in an STL container
- Make sure we destroy the ValueMapCache before verifying the function
in LevelRaise.cpp
