Daniel Dunbar 914bc4106c IRgen/ARM: Fix a think-o in conversion-to-null for member function pointers, we
were computing the conversion as (ptr != 0 && non-virtual), when it should be
(ptr != 0 || is-virtual).
 - Test to follow in LLVM test-suite.

Argyrios Kyrtzidis 1618023018 We regard a function as 'unused' from the codegen perspective, so our warnings diverge from
gcc's unused warnings which don't get emitted if the function is referenced even in an unevaluated context
(e.g. in templates, sizeof, etc.). Also, saying that a function is 'unused' because it won't get codegen'ed
is somewhat misleading.

- Don't emit 'unused' warnings for functions that are referenced in any part of the user's code.
- A warning that an internal function/variable won't get emitted is useful though, so introduce
  -Wunneeded-internal-declaration which will warn if a function/variable with internal linkage is not
  "needed" ('used' from the codegen perspective), e.g:

  static void foo() { }

  template <int>
  void bar() {
    foo();
  }

test.cpp:1:13: warning: function 'foo' is not needed and will not be emitted
static void foo() { }

Peter Collingbourne 133587f08b Add a new expression classification, CL_AddressableVoid
CL_AddressableVoid is the expression classification used for void
expressions whose address can be taken, i.e. the result of [], *
or void variable references in C, as opposed to things like the
result of a void function call.

Douglas Gregor 6c7a9eec42 When providing code completions of ivar names for a property
implementation such as

  @synthesize Prop1 = 

Give priority to ivars whose type matches or closely matches the
property type (as we do for several other kinds of
results). Additionally, if there is an ivar with the same name as the
property, or differs only due to a _ prefix or suffix, give that ivar
a priority bump. Finally, verify that this search is properly
returning ivars within class extensions and implementations
(<rdar://problem/8488854>).

Chris Lattner 97bbee2fb4 Fix a miscompilation I introduced in r129652, thanks for Eli for tracking
it down.  we effectively were compile the testcase into:

void test14(int x) {
  switch (x) {
    case 11: break;
    case 42: test14(97);  // fallthrough
    default: test14(42); break;

which is not the same thing at all.  This fixes a miscompilation of 
MallocBench/gs seen on the clang-x86_64-linux-fnt buildbot.

Anders Carlsson fcaaa697ec When laying out bases in, always try the "base subobject" LLVM type. If it
turns out that a field or base needs to be laid out in the tail padding of
the base, CGRecordLayoutBuilder::ResizeLastBaseFieldIfNecessary will convert
it to an array of i8.

I've audited the new test results to make sure that they are still valid. I've
also verified that we pass a self-host with this change.

This (finally) fixes PR5589!

Douglas Gregor 5d3d3fa33d For the purposes of overload resolution, consider a conversion from an
Objective-C pointer to void* as a "conversion to void*". This allows
us to prefer an Objective-C object pointer conversion to a superclass
object pointer over an Objective-C object pointer conversion to
cv-void*. Fixes PR9735.

Douglas Gregor 39d1a0973d Forbid the use of C++ new/delete to allocate/free objects within an
address space. I could see that this functionality would be useful,
but not in its current form (where the address space is ignored):
rather, we'd want to encode the address space into the parameter list
passed to operator new/operator delete somehow, which would require a
bunch more semantic analysis.

Douglas Gregor b472e93af7 Implement appropriate semantics for C++ casting and conversion when
dealing with address-space- and GC-qualified pointers. Previously,
these qualifiers were being treated just like cvr-qualifiers (in some
cases) or were completely ignored, leading to uneven behavior. For
example, const_cast would allow conversion between pointers to
different address spaces.

The new semantics are fairly simple: reinterpret_cast can be used to
explicitly cast between pointers to different address spaces
(including adding/removing addresss spaces), while
static_cast/dynamic_cast/const_cast do not tolerate any changes in the
address space. C-style casts can add/remove/change address spaces
through the reinterpret_cast mechanism. Other non-CVR qualifiers
(e.g., Objective-C GC qualifiers) work similarly.

As part of this change, I tweaked the "casts away constness"
diagnostic to use the term "casts away qualifiers". The term
"constness" actually comes from the C++ standard, despite the fact
that removing "volatile" also falls under that category. In Clang, we
also have restrict, address spaces, ObjC GC attributes, etc., so the
more general "qualifiers" is clearer.
