This sets the stage 
- to implement function notes as function attributes and 
- to distinguish between function attributes and return value attributes.

This requires corresponding changes in llvm-gcc and clang.

Do not try to update dominator info while manipulating CFG.  This code does not handle all cases and keeps invalid dom info around some cases, which misleads other passes down stream.

Right now, dom info is recaluclated in the end if the loop is switched.
