b12a8a6177 Switch from using CallInst's to represent call sites to using the LLVM 
CallSite class.  Now we can represent function calls by invoke instructions
too!

9d9fd138dc Rework post dominator information so that we do not have to 
unify all exit nodes of a function to compute post-dominance information.
This does not work with functions that have both unwind and return nodes,
because we cannot unify these blocks.  The new implementation is better
anyway. :)

37123e1b58 Simplification of trip counting machinery. 
- make sure to check the indvar type before anything else (efficiency)
  - Make sure to insert the 'add' into the program, even though it'll be
    dead
  - Wrap code at 80 columns
  - Other minor cleanups to reduce indentation level

f72da72785 Rename TarjanSCCIterator -> scc_iterator 
* Increases consistency with other iterators (e.g. df_iterator, po_iterator...)
  * It's shorter
  * We don't name classes by the implementation, we name it for the interface!

39ff8beb24 Improvement to the previous fix: branch following a delay slot of 
another delayed instr. would cause the later sanity-check (assertion)
in PhyRegAlloc.cpp to fail, even though there is really no error.

the instruction as being live before/after the delay slot
instructions as well.
