Step 1 of 2: conditional passes.
Rationale:
The change adds a return value to Run() in preparation of
conditional pass execution. The value returned by Run() is
best effort, returning false means no optimizations were
applied or no useful information was obtained. I filled
in a few cases with more exact information, others
still just return true. In addition, it integrates inlining
as a regular pass, avoiding the ugly "break" into
optimizations1 and optimziations2.
