Alex Lorenz 24952fbc6f Add #pragma clang attribute support to the external_source_symbol attribute
Prior to this commit the external_source_symbol attribute wasn't supported by
#pragma clang attribute for the following two reasons:

- The Named attribute subject hasn't been supported by TableGen.
- There was no way to specify a subject match rule for #pragma clang attribute
 that could operate on a set of attribute subjects (e.g. the ones that derive
 from NamedDecl).

This commit fixes the two issues and thus adds external_source_symbol support to
#pragma clang attribute.

This is a recommit of r300539 that was reverted in r300543 due to test failures.
The original commit message is displayed below:

The new '#pragma clang attribute' directive can be used to apply attributes to
multiple declarations. An attribute must satisfy the following conditions to
be supported by the pragma:
- It must have a subject list that's defined in the TableGen file.
- It must be documented.
- It must not be late parsed.
- It must have a GNU/C++11 spelling.

Erich Keane a32910da1a Correct class-template deprecation behavior-REDUX
Correct class-template deprecation behavior

Based on the comment in the test, and my reading of the standard, a deprecated warning should be issued in the following case:
template<typename T> [[deprecated]] class Foo{}; Foo<int> f;

This was not the case, because the ClassTemplateSpecializationDecl creation did not also copy the deprecated attribute.

Note: I did NOT audit the complete set of attributes to see WHICH ones should be copied, so instead I simply copy ONLY the deprecated attribute.

Justin Lebar 4086fe5cd1 [TableGen] Only normalize the spelling of GNU-style attributes.
Summary:
When Sema looks up an attribute name, it strips off leading and trailing
"__" if the attribute is GNU-style.  That is, __attribute__((foo)) and
__attribute__((__foo__)) are equivalent.

This is only true for GNU-style attributes.  In particular,
__declspec(__foo__) is not equivalent to __declspec(foo), and Sema
respects this difference.

This patch fixes TableGen to match Sema's behavior.  The spelling
'GNU<"__foo__">' should be normalized to 'GNU<"foo">', but
'Declspec<"__foo__">' should not be changed.

This is necessary to make CUDA compilation work on Windows, because e.g.
the __device__ attribute is spelled __declspec(__device__).

Attr.td does not contain any Declspec spellings that start or end with
"__", so this change should not affect any other attributes.

George Burgess IV 8a36ace5b1 [TableGen] Ignore fake args for parsing-related arg counts.
We should complain about the following:

```
void foo() __attribute__((unavailable("a", "b")));
```

Instead, we currently just ignore "b". (...We also end up ignoring "a",
because we assume elsewhere that this attribute can only have 1 or 0
args.)

This happens because `unavailable` has a fake enum arg, and
`AttributeList::{getMinArgs,getMaxArgs}` include fake args in their
counts.

Richard Smith ffa0241a03 Work around a GCC 4.7-specific issue: due to implementing older rules for
implicit declarations of move operations, GCC 4.7 would find that SelectPiece
has neither a move constructor nor a copy constructor. The copy constructor was
(correctly) deleted because the class has a member of move-only type, and the
move constructor was (incorrectly, per current C++ rules) not provided because
the class has a copy-only base class (in turn because it explicitly declares a
destructor).

Eric Fiselier 341e825eae Implement __attribute__((require_constant_initialization)) for safe static initialization.
Summary:
This attribute specifies expectations about the initialization of static and
thread local variables. Specifically that the variable has a
[constant initializer](http://en.cppreference.com/w/cpp/language/constant_initialization)
according to the rules of [basic.start.static]. Failure to meet this expectation
will result in an error.

Static objects with constant initializers avoid hard-to-find bugs caused by
the indeterminate order of dynamic initialization. They can also be safely
used by other static constructors across translation units.

This attribute acts as a compile time assertion that the requirements
for constant initialization have been met. Since these requirements change
between dialects and have subtle pitfalls it's important to fail fast instead
of silently falling back on dynamic initialization.

```c++
  // -std=c++14
  #define SAFE_STATIC __attribute__((require_constant_initialization)) static
  struct T {
    constexpr T(int) {}
    ~T();
  };
  SAFE_STATIC T x = {42}; // OK.
  SAFE_STATIC T y = 42; // error: variable does not have a constant initializer
  // copy initialization is not a constant expression on a non-literal type.
```
This attribute can only be applied to objects with static or thread-local storage
duration.
