Clang: Use PCHs for indexing

Browse Source 
As generating the AST is quite expensive it would be very useful to cache
the not changed include. So we generate PCHs for include outside of a
project part. With this change this PCHs are used by the indexer.

For that they are save to the symbol database by the PCH manager and when
fetched by the symbol indexer.
