* For PR411:Reid Spencer2007-02-05
| | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33918 91177308-0d34-0410-b5e6-96231b3b80d8
