Make LoopInfoBase more generic, in preparation for having MachineLoopInfo.  This involves a small interface change.

This adds redundancy for now.

Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

Remove ImmediateDominator analysis.  The same information can be obtained from DomTree.  A lot of code for
constructing ImmediateDominator is now folded into DomTree construction.

This is part of the ongoing work for PR217.

The critical edge block dominates the dest block if the destblock dominates
all edges other than the one incoming from the critical edge.

a problem in LoopStrengthReduction, where it would split critical edges
then confused itself with outdated loop information.

llvm-svn: 22776

Instead, just update the BB in-place.  This is both faster, and it prevents
split-critical-edges from shuffling the PHI argument list unneccesarily.

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/.
