Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

this speeds up opt --std-compile-opts on 447.dealII by 7.3%.

the Transforms library. This reduces debug library size by 132 KB, debug
binary size by 376 KB, and reduces link time for llvm tools slightly.

Adjust to changes in Module interface:
getMainFunction() -> getFunction("main")
getNamedFunction(X) -> getFunction(X)

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.

Take an incremental step towards type plane elimination. This change
separates types from values in the symbol tables by finally making use
of the TypeSymbolTable class. This yields more natural interfaces for
dealing with types and unclutters the SymbolTable class.
