Fix dumping pre/post preprocessing passes (#2469)

This commit changes the hard-coded list of checks for
preprocessing-related dump tags to take advantage of the new
preprocessing pass registration mechanism from PR #2468. It also fixes a
typo in the `Dump.isOn()` check in `PreprocessingPass::dumpAssertions()`
and adds a list of available passes to the `--dump help` output.
