Enabled relaxed LiveVariables analysis in the path-sensitive engine to increase the coverage of bugs. Primarily affects IdempotentOperationChecker.
- Migrated a temporarily separated test back to its original file (bug has been fixed, null-deref-ps-temp.c -> null-deref-ps.c)
- Changed SymbolManager to use relaxed LiveVariables
- Updated several test cases that the IdempotentOperationChecker class now flags
- Added test case to test relaxed LiveVariables use by the IdempotentOperationChecker

Add alternate version of LiveVariables analysis that does not kill liveness at assignments. This 'relaxed' liveness is useful in path sensitive analysis for situations where the resulting extended liveness allows us to find some bugs.
- Added killAtAssign flag to LiveVariables
- Added relaxed LiveVariables to AnalysisContext with an accessor

Implement CXCursor support for walking C++ base specifiers.  This includes adding the API hooks clang_isVirtualBase() and clang_getCXXAccessSpecifier() to query properties of the base specifier.

Implements <rdar://problem/8274883>.

priority boost to methods with the same selector. 

llvm-svn: 112268

a message send to "super" from a method that appears to be meant to
override a superclass method (same kind, same selector, same argument
types), provide a "super" completion that fills in the selector along
with forwarding the method's arguments (as placeholders).

an '&' expression from the second caller of ActOnIdExpression.

Teach template argument deduction that an overloaded id-expression
doesn't give a valid type for deduction purposes to a non-static
member function unless the expression has the correct syntactic
form.

Teach ActOnIdExpression that it shouldn't try to create implicit
member expressions for '&function', because this isn't a        
permitted form of use for member functions.

Teach CheckAddressOfOperand to diagnose these more carefully.
Some of these cases aren't reachable right now because earlier
diagnostics interrupt them.
