Add an option to enable on-demand parsing of needed ASTs during CTU analysis.
Two options are introduced. CTUOnDemandParsing enables the feature, and
CTUOnDemandParsingDatabase specifies the path to a compilation database, which
has all the necessary information to generate the ASTs. In case an empty
string is given, on-the-fly parsing is disabled.
