Note that it's not clear whether this is the right behavior, please see

Automate attribute argument count semantic checking when there are variadic or optional arguments present. With this, the only time you should have to manually check attribute argument counts is when HasCustomParsing is set to true, or when you have variadic arguments that aren't really variadic (like ownership_holds and friends).

Updating the diagnostics in the launch_bounds test since they have been improved in that case. Adding a test for nonnull since it has little test coverage, but has truly variadic arguments.

Delay check for prototype on __fastcall functions until after MergeFunctionDecl.

In C, it is only known after merging decls if a function with 0 arguments has
a prototype.  Fixes PR20386, see that for more notes.

Add a state variable to the loop hint attribute.

This patch is necessary to support constant expressions which replaces the integer value in the loop hint attribute with an expression. The integer value was also storing the pragma’s state for options like vectorize(enable/disable) and the pragma unroll and nounroll directive. The state variable is introduced to hold the state of those options/pragmas. This moves the validation of the state (keywords) from SemaStmtAttr handler to the loop hint annotation token handler.

Resubmit with changes to try to fix the build-bot issue.

Factor out exception specification information from
FunctionProtoType::ExtProtoInfo. Most of the users of these fields don't care
about the other ExtProtoInfo bits and just want to talk about the exception
specification.

[modules] Maintain an AST invariant across module load/save: if any declaration
of a function has a resolved exception specification, then all declarations of
the function do.

We should probably improve the AST representation to make this implicit (perhaps
only store the exception specification on the canonical declaration), but this
fixes things for now.

The testcase for this (which used to assert) also exposes the actual bug I was
trying to reduce here: we sometimes fail to emit the body of an imported
special member function definition. Fix for that to follow.

Remove this pointer that is converted to bool.  In well-defined contexts, the
this pointer is always non-null.  If the this pointer is null, it is undefined
and the compiler may optimize it away by assuming it is non-null.  The null
checks are pushed into the callers.

[modules] Remove IRGen special case for emitting implicit special members if
they're somehow missing a body. Looks like this was left behind when the loop
was generalized, and it's not been problematic before because without modules,
a used, implicit special member function declaration must be a definition.

This was resulting in us trying to emit a constructor declaration rather than
a definition, and producing a constructor missing its member initializers.

[mips] Defer va_arg expansion to the backend.

Summary:
This patch causes clang to emit va_arg instructions to the backend instead of
expanding them into an implementation itself. The backend already implements
va_arg since this is necessary for NaCl so this patch is removing redundant
code.

Together with the llvm patch (D4556) that accounts for the effect of endianness
on the expansion of va_arg, this fixes PR19612.

Depends on D4556
