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.

David Majnemer c10b8381f7 Update tests touched by r249656 
These test updates almost exclusively around the change in behavior
around enum: enums without a definition are considered incomplete except
when targeting MSVC ABIs.  Since these tests are interested in the
'incomplete-enum' behavior, restrict them to %itanium_abi_triple.

Jordan Rose eaacff4826 [analyzer] More tests for "release and stop tracking". 
Under GC, a release message is ignored, so "release and stop tracking" just
becomes "stop tracking". But CFRelease is still honored. This is the main
difference between ns_consumed and cf_consumed.

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>

Jordy Rose c49ec53e29 [analyzer] Move the knowledge of whether or not GC is enabled for the current analysis from CFRefCount to ExprEngine. 
Remove TransferFuncs from ExprEngine and AnalysisConsumer.

Demote RetainReleaseChecker to a regular checker, and give it the name osx.cocoa.RetainCount (class name change coming shortly). Update tests accordingly.

Chandler Carruth 4c6fdca035 Implement a warning for known shift overflows on constant shift 
expressions. Consider the code:

  int64_t i = 10 << 30;

This compiles fine, but most developers expect it to produce the value
for 10 gigs, not -2 gigs. This is actually undefined behavior because
the LHS is a signed integer type.

The warning is currently gated behind -Wshift-overflow.

There is a special case where only the sign bit is overridden that gets
a custom error message and is by default ignored. This case is much less
likely to cause observed buggy behavior, it's just undefined behavior
according to the spec. This warning can be enabled with
-Wshift-sign-overflow.

Original patch by Oleg Slezberg, with style tweaks and some correctness
fixes by me.

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 5dbfa3fadd Rename attributes: 
'objc_ownership_cfretain' -> 'cf_ownership_retain'

Motivation: Core Foundation objects can be used in isolation from Objective-C,
and this forces users to reason about the separate semantics of CF objects. More
Sema support pending.
