Add FastDSE, a new algorithm for doing dead store elimination. This algorithm is not as accurate
...
as the current DSE, but it only a linear scan over each block, rather than quadratic. Eventually
(once it has been improved somewhat), this will replace the current DSE.
NOTE: This has not yet been extensively tested.

constructing ImmediateDominator is now folded into DomTree construction.

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.

Removing -raise has neglible positive or negative side effects so we are
