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.

Learn from sext and zext. The destination value falls within the range of the
source type.

Generalize properties regarding constant ints.

Get smarter about marking blocks as unreachable. If 1 >= 2 in order for this
block to execute, then it isn't reachable.

X + C to promote LEA formation.  We would incorrectly apply it in some cases
(test) and miss it in others.
