Refine codegen for visibility and hidden.  WIP.

This fixes throwing exceptions inside @catch blocks nested inside outer @try blocks and also fixes jumping from an inner @finally to an outer @finally (via any relevant @catch blocks).

The code exhibiting this bug was based on code from CGObjCMac.  I believe that this bug may still be present on the Mac runtimes, although the test case in the bug contains a few GNUisms and won't compile without some minor tweaks with Apple's libobjc.

Sema and/or CodeGen that need to remove qualifiers. Addresses a
linking issue when building LLVM with Clang.

Currently the builtin still accepts the full range for compatibility.

avoid #including CharUnits.h in ASTContext.h.

Make sure that we mangle overloaded operators that are member functions correctly, giving them the correct arity.

With this seemingly insignificant fix, we are now able to build and link clang using clang itself! (LLVM still has to be built with gcc for the time being).

recursing in CGDebugInfo::CreateTypeNode, teach
CanonicalizeTypeForDebugInfo---now called UnwrapTypeForDebugInfo---to
keep unwrapping the type until we hit something that can be
represented by debug information. Thanks to Anders for pointing this out!

ElaboratedType, QualifiedNameType, and SubstTemplateTypeParmType type

and "typeof" nodes, rather than asserting nondescriptly.

new InitializationSequence. This fixes some bugs (e.g., PR5808),
changed some diagnostics, and caused more churn than expected. What's
new:

  - InitializationSequence now has a "C conversion sequence" category
    and step kind, which falls back to
  - Changed the diagnostics for returns to always have the result type
    of the function first and the type of the expression second.
    CheckSingleAssignmentConstraints to peform checking in C. 
  - Improved ASTs for initialization of return values. The ASTs now
    capture all of the temporaries we need to create, but
    intentionally do not bind the tempoary that is actually returned,
    so that it won't get destroyed twice.
  - Make sure to perform an (elidable!) copy of the class object that
    is returned from a class.
  - Fix copy elision in CodeGen to properly see through the
    subexpressions that occur with elidable copies.
  - Give "new" its own entity kind; as with return values and thrown
    objects, we don't bind the expression so we don't call a
    destructor for it.

Note that, with this patch, I've broken returning move-only types in
C++0x. We'll fix it later, when we tackle NRVO.

Rename GetAddrOfRTTI to GetAddrOfRTTIDescriptor. Remove the overload that takes a CXXRecordDecl since we were just creating a QualType from it anyway.
