Dominic Chen 184c6242fa Reland 4: [analyzer] NFC: Update test infrastructure to support multiple constraint managers 
Summary: Replace calls to %clang/%clang_cc1 with %clang_analyze_cc1 when invoking static analyzer, and perform runtime substitution to select the appropriate constraint manager, per D28952.

Ted Kremenek 776409286b [analyzer] Remove IdempotentOperations checker. 
This checker has not been updated to work with interprocedural analysis,
and actually contains both logical correctness issues but also
memory bugs.  We can resuscitate it from version control once there
is focused interest in making it a real viable checker again.

Anna Zaks 0325646705 [analyzer] Do not report uninitialized value warnings inside swap functions. 
This silences warnings that could occur when one is swapping partially initialized structs. We suppress
not only the assignments of uninitialized members, but any values inside swap because swap could
potentially be used as a subroutine to swap class members.

This silences a warning from std::try::function::swap() on partially initialized objects.
