[C++ Patch] Two literal operator template location fixes

[Paolo Carlini]

Hi,

also in my back queue a few more location fixes (of course ;) Tested 
x86_64-linux.

Thanks, Paolo.

////////////////

/cp
2019-05-21  Paolo Carlini  <paolo.carl...@oracle.com>

        * parser.c (cp_parser_template_declaration_after_parameters): Use
        DECL_SOURCE_LOCATION in literal operator template errors.

/testsuite
2019-05-21  Paolo Carlini  <paolo.carl...@oracle.com>

        * g++.dg/cpp0x/udlit-tmpl-arg-neg2.C: Check locations too.
        * g++.dg/cpp0x/udlit-tmpl-parms-neg.C: Likewise.
