Aaron Ballman 36a5350e51 Distinguish between attributes explicitly written at the request of the user, and attributes implicitly generated to assist in bookkeeping by the compiler. This is done so by table generating a CreateImplicit method for each attribute.
Additionally, remove the optional nature of the spelling list index when creating attributes. This is supported by table generating a Spelling enumeration when the spellings for an attribute are distinct enough to warrant it.

Aaron Ballman ab7691c4ce Removing the notion of TargetAttributesSema and replacing it with one where the parsed attributes are responsible for knowing their target-specific nature, instead of letting Sema figure it out. This is necessary so that __has_attribute can eventually determine whether a parsed attribute applies to the given target or not.

Richard Smith 4c96e99235 PR15300: Support C++11 attributes on base-specifiers. We don't support any such
attributes yet, so just issue the appropriate diagnostics. Also generalize the
fixit for attributes-in-the-wrong-place code and reuse it here, if attributes
are placed after the access-specifier or 'virtual' in a base specifier.

Michael Han 23214e5046 Improve C++11 attribute parsing.
- General C++11 attributes were previously parsed and ignored. Now they are parsed and stored in AST.
- Add support to parse arguments of attributes that in 'gnu' namespace.
- Differentiate unknown attributes and known attributes that can't be applied to statements when emitting diagnostic.

Alexis Hunt 3bc72c1ec2 Reapply r158700 and fixup patches, minus one hunk that slipped through and
caused a crash in an obscure case. On the plus side, it caused me to catch
another bug by inspection.

Jakob Stoklund Olesen e1c0ae6fda Revert r158700 and dependent patches r158716, r158717, and r158731.
The original r158700 caused crashes in the gcc test suite,
g++.abi/vtable3a.C among others. It also caused failures in the libc++
test suite.

Alexis Hunt 7b28cdb3da Improve the specification of spellings in Attr.td.
Note that this is mostly a structural patch that handles the change from the old
spelling style to the new one. One consequence of this is that all AT_foo_bar
enum values have changed to not be based off of the first spelling, but rather
off of the class name, so they are now AT_FooBar and the like (a straw poll on
IRC showed support for this). Apologies for code churn.

Most attributes have GNU spellings as a temporary solution until everything else
is sorted out (such as a Keyword spelling, which I intend to add if someone else
doesn't beat me to it). This is definitely a WIP.

I've also killed BaseCheckAttr since it was unused, and I had to go through
every attribute anyway.

Alexis Hunt a0e54d453b Handle C++11 attribute namespaces automatically.
Now, as long as the 'Namespaces' variable is correct inside Attr.td, the
generated code will correctly admit a C++11 attribute only when it has the
appropriate namespace(s).

Richard Smith 84837d5b5a Add -Wimplicit-fallthrough warning flag, which warns on fallthrough between
cases in switch statements. Also add a [[clang::fallthrough]] attribute, which
can be used to suppress the warning in the case of intentional fallthrough.

Patch by Alexander Kornienko!

The handling of C++11 attribute namespaces in this patch is temporary, and will
be replaced with a cleaner mechanism in a subsequent patch.

Richard Smith c202b2809a Add an AttributedStmt type to represent a statement with C++11 attributes
attached. Since we do not support any attributes which appertain to a statement
(yet), testing of this is necessarily quite minimal.
