Revert r321697 "[libclang] Support querying whether a declaration is invalid" and follow-ups.

This broke test/Index/opencl-types.cl on several buildbots:
http://lab.llvm.org:8011/builders/clang-cmake-aarch64-lld/builds/3294
http://lab.llvm.org:8011/builders/clang-ppc64be-linux-multistage/builds/6498
http://lab.llvm.org:8011/builders/clang-ppc64le-linux-multistage/builds/5239

> [libclang] Support querying whether a declaration is invalid
>
> This is useful for e.g. highlighting purposes in an IDE.
>
> Patch by Nikolai Kosjar.

> Differential Revision: https://reviews.llvm.org/D40072

Also reverting follow-ups that otherwise caused conflicts for the
revert:

r321700 "Fix line endings."
r321701 "Fix more line endings."

r321698 "[libclang] Fix cursors for functions with trailing return type"
> For the function declaration
>
> auto foo5(Foo) -> Foo;
> the parameter tokens were mapped to cursors representing the
> FunctionDecl:
