Anna Zaks 6bab4ef4e8 [analyzer] Replace "-analyzer-ipa" with "-analyzer-config ipa".
The idea is to eventually place all analyzer options under
"analyzer-config". In addition, this lays the ground for introduction of
a high-level analyzer mode option, which will influence the
default setting for IPAMode.

Jordan Rose 07a7ed80cb [analyzer] Don't strip CXXBaseObjectRegions when checking dynamic_casts.
...and /do/ strip CXXBaseObjectRegions when casting to a virtual base class.

This allows us to enforce the invariant that a CXXBaseObjectRegion can always
provide an offset for its base region if its base region has a known class
type, by only allowing virtual bases and direct non-virtual bases to form
CXXBaseObjectRegions.

This does mean some slight problems for our modeling of dynamic_cast, which
needs to be resolved by finding a path from the current region to the class
we're trying to cast to.

Jordan Rose d66bee3f76 [analyzer] Don't inline virtual calls unless we can devirtualize properly.
Previously we were using the static type of the base object to inline
methods, whether virtual or non-virtual. Now, we try to see if the base
object has a known type, and if so ask for its implementation of the method.

Anna Zaks 1a3a247041 [analyzer] Better test cases for explaining where tracking types of
symbolic regions would help.

Thanks to Richard Smith.

Anna Zaks 02ecae9282 [analyzer] dynamic_cast: Better model cast from a reference.
Generate a sink when the dynamic_cast from a reference fails to
represent a thrown exception.
