Not sure why we bother updating FunctionDecl's EndRangeLoc in FunctionDecl::setParams.
EndRangeLoc should always be set to at least the ending paren or brace.
[libclang] Annotation of parameters that got default args from a previous declarations was
broken because the end location of the parameter was the end location of the default arg,
resulting in a source range that could begin in one file and end in another.

Really remove FlatStoreManager and BasicStoreManager, this time from the driver. Also remove associated tests. Sorry for the messy commits; this is the result of a botched Git merge.
[analyzer] Overhaul how the static analyzer expects CFGs by forcing CFGs to be linearized only when used by the static analyzer. This required a rewrite of LiveVariables, and exposed a ton of subtle bugs.
The motivation of this large change is to drastically simplify the logic in ExprEngine going forward.
Some fallout is that the output of some BugReporterVisitors is not as accurate as before; those will
need to be fixed over time. There is also some possible performance regression as RemoveDeadBindings
will be called frequently; this can also be improved over time.
