This patch uses sorted arrays in the CompilationUnitScope to improve
the runtime behavior with large source files where a large number of
dependent types exist and need to be recorded in the
qualifiedReferences, simpleNameReferences and rootReferences.

Lookup of memberTypes by name from a ReferenceBinding does use binary
search logic, too (similar approach as with fields).

Sorting of char[][] is extracted to SortedCharArrays.

CompoundNameVector is removed and replaced by SortedCompoundNameVector.
SimpleNameVector is removed and replaced by SortedSimpleNameVector.
