Also remove the charpred of ElementBase. This gets rid of many redundant charpred checks. It means that incomplete classes from the db are now `Element`s, which is maybe noisy but should not be harmful. Together, these changes give a great reduction in DIL and should help the optimiser. It brings the DIL of `UncontrolledFormatString.ql` down from 43,908 lines to 35,400 lines.

@adityasharad @aibaars: only one (or none) of #232 and #215 should be merged, and we're still testing to find out what it should be. |
Raw classes from the database that are incomplete and should be represented by their complete twin are now allowed to be `Element`s for performance reasons, but this commit prevents them from being `Type`s. It was causing confusion in test results and might also cause confusion in queries.
These two predicates were supposed to be fast but became slow after the recent inlining of `unresolve`.
