which is required given the current setup for template
argument deduction substitution validation, and add a test
case to make sure we don't break it in the future.

parameter type to see what's behind it, so that we don't end up
printing silly things like "float const *" when "const float *" would
make more sense. Also, replace the pile of "isa" tests with a simple
switch enumerating all of the cases, making a few more obvious cases
use prefix qualifiers.

might be more qualified than they appear. Fixes PR7708.

This flag and warning match GCC semantics. Also, move it to -Wextra as this is
a largely cosmetic issue and doesn't seem to mask problems. Subsequent fixes to
the tests which no longer by default emit the warning. Added explicit test
cases for both C and C++ behavior with the warning turned on.

strip cv-qualifiers from the expression's type when the language calls
for it: in C, that's all the time, while C++ only does it for
non-class types.
Centralized the computation of the call expression type in
QualType::getCallResultType() and some helper functions in other nodes
(FunctionDecl, ObjCMethodDecl, FunctionType), and updated all relevant
callers of getResultType() to getCallResultType().
Fixes PR7598 and PR7463, along with a bunch of getResultType() call
sites that weren't stripping references off the result type (nothing
stripped cv-qualifiers properly before this change).

deduction. This requires refactoring the deduction to have access to the Sema
object instead of merely the ASTContext. Still leaves something to be desired
due to poor source location.

QualType to get CVR-qualifiers through array types, and switches the primary
comparison methods to use it. This may allow simplifying some of the callers of
getUnqualifiedArrayType.
Also fix the normalizing of CV-qualification during template deduction to
normalize through arrays and allow a more qualified deduced array type. This
fixes PR5911.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

permits, among other things, ripping apart and reconstructing
templates via partial specialization:
template<typename T>
struct DeepRemoveConst { typedef T type; };
template<typename T>
struct DeepRemoveConst<const T> {
typedef typename DeepRemoveConst<T>::type type;
};
template<template<typename> class TT, typename T>
struct DeepRemoveConst<TT<T> > {
typedef TT<typename DeepRemoveConst<T>::type> type;
};
Also, fix a longstanding thinko in the code handling partial ordering
of class template partial specializations. We were performing the
second deduction without clearing out the results of the first
deduction. It's amazing we got through so much code with such a
horrendous error :(
