* Remove extraneous subsections

mbb as multiple mbb's as needed.

Compare dependence analysis with llvm instructions versus machine instrutions. the  problem with using machine instructions and alias analysis is that aa does not handle tmp instructions.

llvm-svn: 20931

Dependence analyzer that just determines dependences within a loop for loads and stores using alias analysis.

returned integer values all of the way to 64-bits (we only did it to 32-bits
leaving the top bits undefined).  This causes problems for targets like alpha
whose ABI's define the top bits too.
