Reid Kleckner a3fe27f6b5 Revert "[Sema] Warn on attribute nothrow conflicting with language specifiers"
This reverts r314461.

It is warning on user code that uses END_COM_MAP(), which expands to
declare QueryInterface with conflicting exception specifers. I've spent
a while trying to understand why, but haven't been able to extract a
reduced test case. Let's revert and I'll keep trying.

Krasimir Georgiev 6a1c9d51fa [clang-format] Fix regression about short functions after #else
Summary:
This patch fixes a regression introduced in r312904, where the formatter confuses
the `else` in `#else` with an `else` of an `if-else` statement.
For example, formatting this code with google style
```
#ifdef A
int f() {}
#else
int f() {}
#endif
```
resulted in
```
#ifdef A
int f() {}
#else
int f() {
}
#endif
```

Andrew Gozillon 25b16572e9 Dependent Address Space Support Test Fix
Modifying a non-type template integer arguement that is causing errors 
in some builds as it's too large for 32-bit longs. This hopefully (and 
seems to when testing) should fix all of the build bot errors relating 
to this test. I also modified the name of the function call to be more 
apt.

Andrew Gozillon 572bbb0754 Dependent Address Space Support
This patch relates to: https://reviews.llvm.org/D33666 This adds support
for template parameters to be passed to the address_space attribute. 
The main goal is to add further flexibility to the attribute and allow 
for it to be used easily with templates.

The main additions are a new type (DependentAddressSpaceType) alongside 
its TypeLoc and its mangling. As well as the logic required to support 
dependent address spaces which mainly resides in TreeTransform.h and 
SemaType.cpp.

Richard Smith ac63d63543 Add a "vexing parse" warning for ambiguity between a variable declaration and a
function-style cast.

This fires for cases such as

  T(x);

... where 'x' was previously declared and T is a type. This construct declares
a variable named 'x' rather than the (probably expected) interpretation of a
function-style cast of 'x' to T.

Apparently, the MSVC SDK has a strange implementation that

types as well.

Additionally, it corrects the behavior where extern-C++ wrapped around an
Interface-Like type would permit an interface-like type to exist in a namespace.

Alexander Shaposhnikov 195b25cf3c [clang] Add getUnsignedPointerDiffType method
C11 standard refers to the unsigned counterpart of the type ptrdiff_t 
in the paragraph 7.21.6.1p7 where it defines the format specifier %tu.
In Clang (in PrintfFormatString.cpp, lines 508-510) there is a FIXME for this case,
in particular, Clang didn't diagnose %tu issues at all, i.e.
it didn't emit any warnings on the code printf("%tu", 3.14).
In this diff we add a method getUnsignedPointerDiffType for getting the corresponding type
similarly to how it's already done in the other analogous cases (size_t, ssize_t, ptrdiff_t etc)
and fix -Wformat diagnostics for %tu plus the emitted fix-it as well.

Test plan: make check-all

Erich Keane 97dfc4ab28 [Sema] Correct nothrow inherited by noexcept
As reported in https://bugs.llvm.org/show_bug.cgi?id=33235,
a noexcept function was unable to inherit from a nothrow defaulted
constructor. Attribute "nothrow" is supposed to be semantically
identical to noexcept, and in fact, a number of other places in the
code treat them identically.

This patch simply checks the RecordDecl for the correct attribute in
the case where no other exception specifier was set.

Erich Keane c372e15c4e [Sema] Warn on attribute nothrow conflicting with language specifiers
I discovered it was possible to create a 'nothrow' noexcept(false)
function, which is both non-sensical as well as seemingly breaking.

This patch warns if attribute nothrow is used with anything besides "noexcept".

"noexcept(true)" isn't possible, because the noexcept decl isn't parsed until
later.
