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>.

Anna Zaks 699f55b98c [analyzer] Fix a false positive in the CFArrayCreate check that surfaces
the the code like this (due to x and &x being the same value but
different size):

void* x[] = { ptr1, ptr2, ptr3 };
CFArrayCreate(NULL, (const void **) &x, count, NULL);

Anna Zaks 06f10bf05a [analyzer] Add an AST checker that checks for a common pitfall when
using CFArrayCreate & family.

Specifically, CFArrayCreate's input should be:
'A C array of the pointer-sized values to be in the new array.'
