According to the dEQP tests, a macro replacement list generated by a
function-like macro invocation should get its location from the closing
parenthesis of the invocation. The tests check this by using __LINE__ in
a macro with a multi-line invocation. It's not quite clear from the spec
that the enforced behavior is expected as opposed to the replacement
list getting its location from the macro name, but a minor correction to
the preprocessor makes the dEQP tests pass.

Newlines in the preprocessor unit tests are generated according to the
source locations in the token list produced by the preprocessor, so the
expectations of a few tests also need to be updated.
