Enhance reference-count checker to correctly identify CG "release" functions.  This fixes <rdar://problem/6303488>.

Fix <rdar://problem/6257675> error: member reference base type ('NSUserDefaults *') is not a structure or union.

Teach Sema::ActOnMemberReferenceExpr() to look through local category implementations associated with the class.

Seriliazation of base class specifiers is not yet implemented.

Clean up handing of DeclRefExprs in Expr::isLvalue and refactor part
of the check into a static DeclCanBeLvalue.

conversions (e.g., comparing int* -> const int* against 
int* -> const volatile int*); see C++ 13.3.3.2p3 bullet 3.

Add Sema::UnwrapSimilarPointerTypes to simplify the control flow of
IsQualificationConversion and CompareQualificationConversion (and fix
the handling of the int* -> volatile int* conversion in the former).

1. Remove a bogus assertion, clients other than sema can return a
   null pointer from actions that result in ParseTypeName returning null.
2. Remove dead RParenLoc variable.
3. Simplify control flow handling error conditions.
4. On a major failure, we should skip until ')' not until '}'.

 - Stop playing fast and loose with the std stream.

Fix a thinko in the qualification-conversion check when the qualificaitons are disjoint, and add some overloading-based tests of qualification conversions

 - Split backend related consumer out into Backend.cpp, replaces
   LLVMCodeGenWriter.
 - Structure follows llvm-gcc to some extent.
 - Still need to implement all the options which impact code
   generation and the optimization passes which llvm-gcc uses at
   various levels.

Changes:
  - Sema::IsQualificationConversion determines whether we have a qualification
    conversion.
  - Sema::CheckSingleAssignment constraints now follows the C++ rules in C++,
    performing an implicit conversion from the right-hand side to the type of
    the left-hand side rather than checking based on the C notion of 
    "compatibility". We now rely on the implicit-conversion code to
    determine whether the conversion can happen or
    not. Sema::TryCopyInitialization has an ugly reference-related
    hack to cope with the initialization of references, for now.
  - When building DeclRefExprs, strip away the reference type, since
    there are no expressions whose type is a reference. We'll need to
    do this throughout Sema.
  - Expr::isLvalue now permits functions to be lvalues in C++ (but not
  in C).

When conjuring symbols for compound assignments, use the promoted type to determine if the symbolic value as a "loc::" or "nonloc::" value.

ASTContext::isObjCObjectPointerType() needs to consider blocks as objects.

Handle [NSAutoreleasePool addObject:] (an alternative way to add objects to the current autorelease pool).

Tweak an expected-error to match the output. IMHO it is better to diagnose 'int (void)' because it has the same meaning in C and C++.

Fix <rdar://problem/6265257> warnings for ambiguous message send swamp other warnings.

Reworked Sema::MatchTwoMethodDeclarations() to optionally match based on method size and alignment (the default in GCC). Changed Sema::LookupInstanceMethodInGlobalPool() to use this feature.

Added -Wno-struct-selector-match to driver, however didn't hook it up yet. Added a FIXME that says this.

GRExprEngine::VisitCast() so that other parts of the analyzer can be ignorant.
When we cast "array of type T" to "pointer to T", we get the loc::MemRegionVal
corresponding to the array variable. This is sufficient for BasicStore, but not
for RegionStore. RegionStore should get the element region for the first array
element in the cast. So next comes to the revamping of transfer functions for
different store model.
