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 722398f1d4 Fix analyzer tests.

Ted Kremenek 9bf9af92a4 Allow multiple PathDiagnosticConsumers to be used with a BugReporter at the same time. 
This fixes several issues:

- removes egregious hack where PlistDiagnosticConsumer would forward to HTMLDiagnosticConsumer,
but diagnostics wouldn't be generated consistently in the same way if PlistDiagnosticConsumer
was used by itself.

- emitting diagnostics to the terminal (using clang's diagnostic machinery) is no longer a special
case, just another PathDiagnosticConsumer.  This also magically resolved some duplicate warnings,
as we now use PathDiagnosticConsumer's diagnostic pruning, which has scope for the entire translation
unit, not just the scope of a BugReporter (which is limited to a particular ExprEngine).

As an interesting side-effect, diagnostics emitted to the terminal also have their trailing "." stripped,
just like with diagnostics emitted to plists and HTML.  This required some tests to be updated, but now
the tests have higher fidelity with what users will see.

There are some inefficiencies in this patch.  We currently generate the report graph (from the ExplodedGraph)
once per PathDiagnosticConsumer, which is a bit wasteful, but that could be pulled up higher in the
logic stack.  There is some intended duplication, however, as we now generate different PathDiagnostics (for the same issue)
for different PathDiagnosticConsumers.  This is necessary to produce the diagnostics that a particular
consumer expects.

Argyrios Kyrtzidis 2d3905ffac [analyzer] Use the new registration mechanism on some of the experimental checks. These are: 
CStringChecker
   ChrootChecker
   MallocChecker
   PthreadLockChecker
   StreamChecker
   UnreachableCodeChecker

MallocChecker creates implicit dependencies between checkers and needs to be handled differently.
