551ccae044 Changes For Bug 352
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

a000279a7d Implement DeadStoreElim/alloca.llx by observing that allocas are dead at the
end of the function (either return or unwind)

70e9b59b0e * Substantially simplify how free instructions are handled (potentially fixing
a bug in DSE).
* Delete dead operand uses iteratively instead of recursively, using a
  SetVector.
* Defer deletion of dead operand uses until the end of processing, which means
  we don't have to bother with updating the AliasSetTracker.  This speeds up
  DSE substantially.

0fb56afab1 This is a trivial dead store elimination pass. It very very simple and
can be improved in many ways.  But: stop laughing, even with -basicaa it
deletes 15% of the stores in 252.eon :)
