ClangCodeModel: Speed up compilation db generation

Browse Source 
We needlessly re-evaluated the same compiler options again and again for
all files in a project part.
Now we only do the actual file-related work per file. Along the way, we
dissolved some unneeded classes and made CompilerOptionsBuilder non-
polymorphic.
