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.

Devin Coughlin 0bee1d7ff1 [analyzer] Remove ObjCContainersChecker size information when a CFMutableArrayRef escapes 
Update ObjCContainersChecker to be notified when pointers escape so it can
remove size information for escaping CFMutableArrayRefs. When such pointers
escape, un-analyzed code could mutate the array and cause the size information
to be incorrect.

David Blaikie 282ad876bd Implement GCC's -Wint-to-pointer-cast. 
This implementation doesn't warn on anything that GCC doesn't warn on with the
exception of templates specializations (GCC doesn't warn, Clang does). The
specific skipped cases (boolean, constant expressions, enums) are open for
debate/adjustment if anyone wants to demonstrate that GCC is being overly
conservative here. The only really obvious false positive I found was in the
Clang regression suite's MPI test - apparently MPI uses specific flag values in
pointer constants. (eg: #define FOO (void*)~0)

Ted Kremenek 3f58774c8d Fix off-by-one bug in diagnostic prose of ObjCContainersASTChecker. 
While the check itself should count 0-based for the parameter index,
the diagnostic should be 1-based (first, second, third, not start at 0).

Fixes <rdar://problem/12249569>.

CFArrayCreate(NULL, (const void **) &x, count, NULL);
