[PR87013] check for .loc is_stmt support in the assembler

Back when we had the logic to output is_stmt but never exercised it,
it didn't matter that we didn't test for assembler support for it.
But there are still assemblers out there that do not support it, so
now that we enable the formerly latent is_stmt logic, we'd better make
sure the assembler can deal with it.

        * configure.ac: Check for .loc is_stmt support.
        * configure, config.in: Rebuilt.
        * dwarf2out.c (dwarf2out_source_line): Skip is_stmt
        if not supported.
