Kristof Umann 0f9e530c0f [analyzer] Enable control dependency condition tracking by default

Csaba Dabis 693936ab8f [analyzer] CastValueChecker: Model casts 
Summary:
It models the LLVM casts:
- `cast<>`
- `dyn_cast<>`
- `cast_or_null<>`
- `dyn_cast_or_null<>`

It has a very basic support without checking the `classof()` function.

(It reapplies the reverted 'llvm-svn: 365582' patch with proper test file.)
