This happened because deadargelim now causes VMCore to auto-rename every
function that it hacks arguments out of.  Because it hacks arguments out of
functions in a non-deterministic order, this caused the resultant numbering
to be nondet.  The fix is to just be careful to not rename functions!

std::map of std::vector's (ouch!).  This speeds up mem2reg by 10% on 176.gcc.

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.

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.
