Douglas Gregor fcafc6e3de Implement the initial part of C++0x [expr.const]p2, which specifies
that the unevaluated subexpressions of &&, ||, and ? : are not
considered when determining whether the expression is a constant
expression. Also, turn the "used in its own initializer" warning into
a runtime-behavior warning, so that it doesn't fire when a variable is
used as part of an unevaluated subexpression of its own initializer.

Fixes PR9999.

Douglas Gregor 89f3cd5c15 Clean up our handling of template-ids that resolve down to a single
overload, so that we actually do the resolution for full expressions
and emit more consistent, useful diagnostics. Also fixes an IRGen
crasher, where Sema wouldn't diagnose a resolvable bound member
function template-id used in a full-expression (<rdar://problem/9108698>).

Douglas Gregor b327eac117 Implement C++0x [expr.static.cast]p9, which permits explicitly casting
a scoped enumeration type to an integral or floating type,
properly. There was an over-eager assertion, and it was missing the
floating-point case.

Fixes PR9107/<rdar://problem/8937402>.

John McCall 351762cda2 A few more tweaks to the blocks AST representation:
- BlockDeclRefExprs always store VarDecls
  - BDREs no longer store copy expressions
  - BlockDecls now store a list of captured variables, information about
    how they're captured, and a copy expression if necessary
    
With that in hand, change IR generation to use the captures data in       
blocks instead of walking the block independently.        

Additionally, optimize block layout by emitting fields in descending
alignment order, with a heuristic for filling in words when alignment
of the end of the block header is insufficient for the most aligned
field.

Douglas Gregor 582813596a Fix a horrible bug in our handling of C-style casting, where a C-style
derived-to-base cast that also casts away constness (one of the cases
for static_cast followed by const_cast) would be treated as a bit-cast
rather than a derived-to-base class, causing miscompiles and
heartburn.

Fixes <rdar://problem/8913298>.

Douglas Gregor f30101186f Implement substitution of a function parameter pack for its set of
instantiated function parameters, enabling instantiation of arbitrary
pack expansions involving function parameter packs. At this point, we
can now correctly compile a simple, variadic print() example:

  #include <iostream>
  #include <string>

  void print() {}

  template<typename Head, typename ...Tail>
  void print(const Head &head, const Tail &...tail) {
    std::cout << head;
    print(tail...);
  }

    std::string hello = "Hello";
    print(hello, ", world!", " ", 2011, '\n');

Douglas Gregor 6642ca217e Implement semantic analysis for C++ [expr.new]p18-20, which describe
how we find the operator delete that matches withe operator new we
found in a C++ new-expression.

This will also need CodeGen support. On a happy note, we're now a
"nans" away from building tramp3d-v4.

Douglas Gregor e6565625f4 Migrate the mish-mash of declaration checks in
Sema::ActOnUninitializedDecl over to InitializationSequence (with
default initialization), eliminating redundancy. More importantly, we
now check that a const definition in C++ has an initilizer, which was
an #if 0'd code for many, many months. A few other tweaks were needed
to get everything working again:

  - Fix all of the places in the testsuite where we defined const
    objects without initializers (now that we diagnose this issue)
  - Teach instantiation of static data members to find the previous
    declaration, so that we build proper redeclaration
    chains. Previously, we had the redeclaration chain but built it
    too late to be useful, because...
  - Teach instantiation of static data member definitions not to try
    to check an initializer if a previous declaration already had an
    initializer. This makes sure that we don't complain about static
    const data members with in-class initializers and out-of-line
    definitions.
  - Move all of the incomplete-type checking logic out of
    Sema::FinalizeDeclaratorGroup; it makes more sense in
    ActOnUnitializedDecl.

There may still be a few places where we can improve these
diagnostics. I'll address that as a separate commit.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- 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).
