Vikram S. Adve 94c8e5da41 Add support for a top-down propagation pass: 
-- Save a copy of the original call nodes in DSGraph before inlining bottom-up.
-- Also, save a list of the callers of each function in DSGraph.

Vikram S. Adve 4eac78e660 Add support for a top-down propagation pass. 
Each DSGraph now keeps a list of pending callers that have not
been inlined into the function represented by that graph.
It also keeps a copy of the original call nodes before the BU pass
eliminates some of them.

Chris Lattner f31527cd6f * s/method/function 
* BIG CHANGE: The root of the call "graph" is considered to be the external
  node, not the "Root".  This means that users using graph iterators like
  df_begin() will start from the external node.

Chris Lattner 72f9a86d1e Only functions with external linkage can be resolved to function declarations. 
This change fixes programs that have multiple functions named the same thing,
where are least one of them is static/internal.

Chris Lattner 60ebba51c4 * Remove dead code from ExprTypeConvert.cpp 
- I->use_empty() can never be true because of the IHolder's
* Fix bug: test/Regression/Transforms/LevelRaise/2002-07-16-SourceAndDestCrash.ll
   - 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
