Douglas Gregor c7acfdfe9a Add QualifiedDeclRefExpr, which retains additional source-location
information for declarations that were referenced via a qualified-id,
e.g., N::C::value. We keep track of the location of the start of the
nested-name-specifier. Note that the difference between
QualifiedDeclRefExpr and DeclRefExpr does have an effect on the
semantics of function calls in two ways:
  1) The use of a qualified-id instead of an unqualified-id suppresses
     argument-dependent lookup
  2) If the name refers to a virtual function, the qualified-id
  version will call the function determined statically while the
  unqualified-id version will call the function determined dynamically
  (by looking up the appropriate function in the vtable).

Neither of these features is implemented yet, but we do print out
qualified names for QualifiedDeclRefExprs as part of the AST printing.

Douglas Gregor 2eedc3aa1c Add support for member references (E1.E2, E1->E2) with C++ semantics,
which can refer to static data members, enumerators, and member
functions as well as to non-static data members.

Implement correct lvalue computation for member references in C++. 
Compute the result type of non-static data members of reference type properly.

Chris Lattner f3d3faeca6 Rename NamedDecl::getName() to getNameAsString(). Replace a bunch of
uses of getName() with uses of getDeclName().  This upgrades a bunch of
diags to take DeclNames instead of std::strings.

This also tweaks a couple of diagnostics to be cleaner and changes
CheckInitializerTypes/PerformInitializationByConstructor to pass
around DeclarationNames instead of std::strings.

Daniel Dunbar 9b1335eca8 Fix redundant load of bit-fields on assignment (to get the updated
value).
 - Use extra argument to EmitStoreThroughLValue to provide place to
   write update bit-field value if caller requires it.
 - This fixes several FIXMEs.

Douglas Gregor 993603d80d Add a new expression node, CXXOperatorCallExpr, which expresses a
function call created in response to the use of operator syntax that
resolves to an overloaded operator in C++, e.g., "str1 +
str2" that resolves to std::operator+(str1, str2)". We now build a
CXXOperatorCallExpr in C++ when we pick an overloaded operator. (But
only for binary operators, where we actually implement overloading)

I decided *not* to refactor the current CallExpr to make it abstract
(with FunctionCallExpr and CXXOperatorCallExpr as derived
classes). Doing so would allow us to make CXXOperatorCallExpr a little
bit smaller, at the cost of making the argument and callee accessors
virtual. We won't know if this is going to be a win until we can parse
lots of C++ code to determine how much memory we'll save by making
this change vs. the performance penalty due to the extra virtual
calls.

Daniel Dunbar f7fb75044f Easy IRgen improvement for bitfields, don't emit x >> 0.
- Logic such as this quite possibly should be optional builder
   behavior.

Daniel Dunbar b35174727f Lift CodeGenFunction::EmitPredefinedFunctioName out of EmitPredefinedLValue.
- Shouldn't assume predefined expr is a function printing one.
 - Uses CGM functionality to cache function names per module.
