Introduce and use Decl::getAsFunction() to simplify templated function checks

Lift the getFunctionDecl() utility out of the parser into a general
Decl::getAsFunction() and use it to simplify other parts of the implementation.

Reduce isFunctionOrFunctionTemplate() to a simple type check that works the
same was as the other is* functions and move unwrapping of shadowed decls to
callers so it doesn't get run twice.

Shuffle around canSkipFunctionBody() to reduce virtual dispatch on ASTConsumer.
There's no need to query when we already know the body can't be skipped.

We wouldn't lock an inheritance model if we saw a pointer-to-member

Enhance attribute 'nonnull' to be applicable to parameters directly (infix).

This allows the following syntax:

  void baz(__attribute__((nonnull)) const char *str);

instead of:

  void baz(const char *str) __attribute__((nonnull(1)));

This also extends to Objective-C methods.

The checking logic in Sema is not as clean as I would like.  Effectively
now we need to check both the FunctionDecl/ObjCMethodDecl and the parameters,
so the point of truth is spread in two places, but the logic isn't that
cumbersome.
