I meant in doubt 'Left side wins'.
For example 'somethingA+somethingB' and both types are
longint it should return somethingA.
Since codetools do not yet support operator overloading it can't
resolve correctly 'someMatrix'+'someVector'. It should
deterministically return left side, because the important type usually
is at the beginning.

The list is seldom edited so editing does not need much speed.
Fast search is important. As long as there are only 20 types the
structure is irrelevant. But when we extend the list for all types of
the FPC packages the list gets big.
