At some point, pass definitions were heavily macro-ized. Pass descriptive names were added in two places. This is not only redundant but a source of confusion. You could waste a lot of time grepping for the wrong string. I removed all the getName() overrides which, at around 90 passes, was a fairly significant amount of code bloat. Any pass that we want to be able to invoke by name from a tool (sil-opt) or pipeline plan *should* have unique type name, enum value, commend-line string, and name string. I removed a comment about the various inliner passes that contradicted that. Side note: We should be consistent with the policy that a pass is identified by its type. We have a couple passes, LICM and CSE, which currently violate that convention.
