  Log Message:
  -----------
  [GVN] Move `ValueTable` out of `GVN.h` (NFC)

  * Rename `GVNPass::ValueTable` to `GVNValueTable`, and move it out to
    the `llvm`  namepace and to its own file `GVNValueTable.h`
  * Move `GVNPass::Expression` into `llvm::GVNValueTable`.
  * Move `GVNHoistPass` and `GVNSinkPass` to their own headers.

With these changes `GVHoist.cpp` and `GVNSink.cpp` no longer need
to include `GVN.h` or peek into `GVNPass` internals.
