into pretty much everything about overload resolution in order to wean
BuildDeclarationNameExpr off LookupResult::getAsSingleDecl(). Replace
UnresolvedFunctionNameExpr with UnresolvedLookupExpr, which generalizes the
idea of a non-member lookup that we haven't totally resolved yet, whether by
overloading, argument-dependent lookup, or (eventually) the presence of
a function template in the lookup results.
Incidentally fixes a problem with argument-dependent lookup where we were
still performing ADL even when the lookup results contained something from
a block scope.
Incidentally improves a diagnostic when using an ObjC ivar from a class method.
This just fell out from rewriting BuildDeclarationNameExpr's interaction with
lookup, and I'm too apathetic to break it out.
The only remaining uses of OverloadedFunctionDecl that I know of are in
TemplateName and MemberExpr.

specification of 'assign' (no warning to be issued),
when a continuation class makes a 'readonly' attribute
'readwrite' but also specifies the 'assign' attribute.
(this matches gcc's behavior and prevents exessive
warnings)/

super class of the two and qualifies the resulting type by the
intersection of the protocl qualifier list of the two objective-c
pointer types. ( this is continuation of radar 7334235).

in legacy code using dot field access notation (as noted in the test case)
but unrelated to this patch.

1) Issue digsnostics in non-fragile ABI, when an expression
evaluates to an interface type (except when it is used to
access a non-fragile ivar).
2) Issue unsupported error in fragile ABI when an expression
evaluates to an interface type (except when it is used to
access a fragile ivar).

is found. Instead of complaining about a generic "unused expr",
emit:
t.m:7:3: warning: property access result unused - getters should not have side effects
While objc property getters *could* have side effects, according to
the language best practices, they *shouldn't*. Hopefully the
diagnostic now gets this across.

declarations (and not function pointers). This is consistent with GCC. Accepting
this attribute on function pointers means that the attribute should be treated
as a type qualifier, which apparently is not what GCC does. We obviously can
change this later should we desire to enhance the 'malloc' attribute in this
way.

attaching to Objective-C methods (which mirrors GCC's behavior) and to allow the
return type of the function to be an Objective-C pointer or Block pointer (which
GCC also accepts).
Along the way, add 'const' to some of the pointer arguments of various utility
functions...
