12663c4a66 Fix Transforms/DeadArgElim/2007-02-07-FuncRename.ll, fallout from PR411. 
This happened because deadargelim now causes VMCore to auto-rename every
function that it hacks arguments out of.  Because it hacks arguments out of
functions in a non-deterministic order, this caused the resultant numbering
to be nondet.  The fix is to just be careful to not rename functions!

474d7b219d redesign the primary datastructure used by mem2reg to eliminate an 
std::map of std::vector's (ouch!).  This speeds up mem2reg by 10% on 176.gcc.

5fee493a8c With the last change, we no longer need both directions of mapping from 
BBNumbers.  Instead of using a bi-directional mapping, just use a single
densemap.  This speeds up mem2reg on 176.gcc by 8%, from  1.3489 to
1.2485s.

8749d297f5 Apply the VISIBILITY_HIDDEN field to the remaining anonymous classes in 
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.

6af21b3029 For PR411: 
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.

591bfa1e0b Changes to support making the shift instructions be true BinaryOperators. 
This feature is needed in order to support shifts of more than 255 bits
on large integer types.  This changes the syntax for llvm assembly to
make shl, ashr and lshr instructions look like a binary operator:
   shl i32 %X, 1
instead of
   shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.

618f24b0ed Fix bugs in the inliner having to do with single-entry phi nodes and valuemap 
updating.  These were exposed by Devang's recent passmgr changes (with
non-default passorderings) because now the inliner can be interleved with
the LCSSA pass.
