Sema: do not warn about unused const vars if main file is a header

Authored by erikjv on Oct 26 2016, 7:52 AM.



If we pass a header to libclang, e.g. because it's open in an editor in
an IDE, warnings about unused const vars are not useful: other files
that include the header might use those constants. So when -x *-header
is passed as command-line option, suppress this warning.

This makes sense. While variable definitions in a header are weird, the warning that they're unused isn't adding any value.

Doesn't look clang-formatted.
