f1bed4c720 1. Sort switch cases using APInt safe comparison. 
2. Make sure debug output of APInt values is safe for all bit widths.

dbab386e23 Fix a significant algorithm problem with the instcombine worklist. removing 
a value from the worklist required scanning the entire worklist to remove all
entries.  We now use a combination map+vector to prevent duplicates from
happening and prevent the scan.  This speeds up instcombine on a large file
from the llvm-gcc bootstrap from 189.7s to 4.84s in a debug build and from
5.04s to 1.37s in a release build.

3cfc1d22b2 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!
