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.

Dominic Chen 1a154e082c [analyzer] Drop explicit mention of range constraint solver 
Summary: The basic constraint solver was dropped in rL162384, leaving the range constraint solver as the default and only constraint solver. Explicitly specifying it is unnecessary, and makes it difficult to test with other solver backends.

Ted Kremenek a056d62961 Remove BasicConstraintManager. It hasn't been in active service for a while. 
As part of this change, I discovered that a few of our tests were not testing
the RangeConstraintManager.  Luckily all of those passed when I moved them
over to use that constraint manager.

Patrick Beard acfbe9e1f2 Added a new attribute, objc_root_class, which informs the compiler when a root class is intentionally declared. 
The warning this inhibits, -Wobjc-root-class, is opt-in for now. However, all clang unit tests that would trigger
the warning have been updated to use -Wno-objc-root-class. <rdar://problem/7446698>

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. 
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Ted Kremenek 005e8a06f2 Cleanups and fixes to the nil-receiver checker, some of it fallout the 
initial transition of the nil-receiver checker to the Checker
interface as done in r89745.  Some important changes include:

1) We consolidate the BugType object used for nil receiver bug
reports, and don't include the type of the returned value in the
BugType (which would be wrong if a nil receiver bug was reported more
than once)

2) Added a new (temporary) flag to CheckerContext: DoneEvauating.
This is used by GRExprEngine when evaluating message expressions to
not continue evaluating the message expression if this flag is set.
This flag is currently set by the nil receiver checker.  This is an
intermediate solution to allow the nil-receiver checker to properly
work as a plug-in outside of GRExprEngine.  Basically, this flag
indicates that the entire message expression has been evaluated, not
just a precondition (which is what the nil-receiver checker does).
This flag *should not* be repurposed for general use, but just to pull
more things out of GRExprEngine that already in there as we devise a
better interface in the Checker class.

3) Cleaned up the logic in the nil-receiver checker, making the
control-flow a lot easier to read.

Ted Kremenek 4ef13f8ac9 Add clang-cc option "--analyzer-experimental-internal-checks". This

around for a little while for regression testing.

Ted Kremenek 8b0dba358a Fix: <rdar://problem/6740387>. Sending nil to an object that returns a struct 
should only be an error if that value is consumed. This fix was largely
accomplished by moving 'isConsumedExpr' back to ParentMap.
