Generate code for loops formed with the new builder
Adapt the existing counted loop analysis and range/null check
elimination code to work with the new loop building heuristics.
Cleaned up the old ad-hoc loop builder.
Suspend polling is enabled by default for loops. The backward chaining
cell will be used in self-verification and profiling mode.
If the loop includes accesses to resolved fields/classes, abort code
generation for now and revert to the basic acyclic trace. Added
tests/090-loop-formation to make sure the JIT won't choke on such
instructions.
