George Karpenkov 367fbfcc20 [Analyzer] Re-apply r314820 with a fix for StringRef lifetime. 
Fixes the test failure: temporary is now bound to std::string, tests
fully pass on Linux.

This reverts commit b36ee0924038e1d95ea74230c62d46e05f80587e.

George Karpenkov fec6b1afe6 [Analyzer] More granular special casing in RetainCountChecker 
Only assume that IOBSDNameMatching and friends increment a reference counter
if their return type is a CFMutableDictionaryRef.

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.

Anna Zaks 99394bbd02 [analyzer] Fix a crash in RetainCountChecker - we should not rely on CallEnter::getCallExpr to return non-NULL 
We get a CallEnter with a null expression, when processing a destructor. All other users of
CallEnter::getCallExpr work fine with null as return value.

(Addresses PR15832, Thanks to Jordan for reducing the test case!)

Jordan Rose d65f1c8d6e [analyzer] RetainCountChecker: don't assume all functions have names. 
Fixes a hard-to-reach crash when calling a non-member overloaded operator
with arguments that may be callbacks.

Future-proofing: don't make the same assumption in MallocSizeofChecker.
Aside from possibly respecting attributes in the future, it might be
possible to call 'malloc' through a function pointer.

I audited all other uses of FunctionDecl::getIdentifier() in the analyzer;
they all now correctly test to see if the identifier is present before
using it.

Anna Zaks 90ab9bfa11 [analyzer]Malloc,RetainRelease: Allow pointer to escape via NSMapInsert. 
Fixes a false positive (radar://11152419). The current solution of
adding the info into 3 places is quite ugly. Pending a generic pointer
escapes callback.

John McCall 525f05597f Tweak the interface for analyzing the CF conventions for a name 
to take a FunctionDecl* instead of an llvm::StringRef.  Eventually
we might push more logic in there, like using slightly different
conventions for C++ methods.

Also, fix a bug where 'copy' and 'create' were being caught in 
non-camel-cased strings.  We want copyFoo and CopyFoo and XCopy
but not Xcopy or xcopy.

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.
