Benjamin Kramer 724afa5a33 [analyzer] Inline StringSet that's defined in a header
That's just asking for ODR violations. Also drop a call to lower()
that's not needed.

Kirstóf Umann bda3dd0d98 [analyzer][NFC] Change LangOptions to CheckerManager in the shouldRegister* functions
Some checkers may not only depend on language options but also analyzer options.
To make this possible this patch changes the parameter of the shouldRegister*
function to CheckerManager to be able to query the analyzer options when
deciding whether the checker should be registered.

Artem Dergachev 44820630df [analyzer] NFC: Change evalCall() to provide a CallEvent.
This changes the checker callback signature to use the modern, easy to
use interface. Additionally, this unblocks future work on allowing
checkers to implement evalCall() for calls that don't correspond to any
call-expression or require additional information that's only available
as part of the CallEvent, such as C++ constructors and destructors.

Artem Dergachev eb71c0c961 [analyzer] SmartPtrModeling: Fix a null dereference.
Don't crash when trying to model a call in which the callee is unknown
in compile time, eg. a pointer-to-member call.

Artem Dergachev 8c6119a442 [analyzer] PR41269: Add a bit of C++ smart pointer modeling.
Implement cplusplus.SmartPtrModeling, a new checker that doesn't
emit any warnings but models methods of smart pointers more precisely.

For now the only thing it does is make `(bool) P` return false when `P`
is a freshly moved pointer. This addresses a false positive in the
use-after-move-checker.
