Add a warning to TableGen for unused template arguments in classes and
multiclasses, for example:
multiclass Foo<int x> {
def bar;
}
$ llvm-tblgen foo.td
foo.td:1:20: warning: unused template argument: Foo::x
multiclass Foo<int x> {
^
A flag '--no-warn-on-unused-template-args' is added to disable the
warning. The warning is disabled for LLVM and sub-projects if
'LLVM_ENABLE_WARNINGS=OFF'.
