Dominic Chen 2cfd901321 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 75a2f6b798 [analyzer] Discard malloc-overflow bug-report when a known size is malloc'ed.
This patch ignores malloc-overflow bug in two cases:
Case1:
x = a/b; where n < b
malloc (x*n); Then x*n will not overflow.

Case2:
x = a; // when 'a' is a known value.
malloc (x*n);

Also replaced isa with dyn_cast.

Reject multiplication by zero cases in MallocOverflowSecurityChecker
Currently MallocOverflowSecurityChecker does not catch cases like:
malloc(n * 0 * sizeof(int));

This patch rejects such cases.

Two test cases added. malloc-overflow2.c has an example inspired from a code
in linux kernel where the current checker flags a warning while it should not.

A patch by Aditya Kumar!
