4807e07fff Adjust testcase to make it more stable across visitation order changes,
unbreaking it after r61024.

f33131685b make GVN try to rename inputs to the resultant replaced values, which
cleans up the generated code a bit.  This should have the added benefit of
not randomly renaming functions/globals like my previous patch did. :)

This is in release mode. To replicate, compile llvm and llvm-gcc in optimized
mode. Then build llvm, in optimized mode, with the newly created compiler.

879922932f make RLE preserve the name of the load that it replaces. This is just
a pretification of the IR.

45537917ee Fix a couple more bugs in the phi construction by pulling in code that does
almost the same things from LCSSA.
