f35a1dbc7a Remove ImmediateDominator analysis. The same information can be obtained from DomTree. A lot of code for 
constructing ImmediateDominator is now folded into DomTree construction.

This is part of the ongoing work for PR217.

430c9217f0 redesign the primary datastructure used by mem2reg to eliminate an 
std::map of std::vector's (ouch!).  This speeds up mem2reg by 10% on 176.gcc.

c85e79f3e0 With the last change, we no longer need both directions of mapping from 
BBNumbers.  Instead of using a bi-directional mapping, just use a single
densemap.  This speeds up mem2reg on 176.gcc by 8%, from  1.3489 to
1.2485s.

3aaaa0b2bd For PR411: 
This patch replaces the SymbolTable class with ValueSymbolTable which does
not support types planes. This means that all symbol names in LLVM must now
be unique. The patch addresses the necessary changes to deal with this and
removes code no longer needed as a result. This completes the bulk of the
changes for this PR. Some cleanup patches will follow.
