Treat -g1 as -gline-tables-only -g1 on gcc (and also IBM's xlc) are documented to be very similar to -gline-tables-only. Our -gline-tables-only might still be more verbose than -g1 on other compilers, but currently we treat -g1 as -g, and so we're producing much more debug info at -g1 than everybody else. Treating -g1 as -gline-tables-only brings us much closer to what everyone else is doing. For more information, see the discussion on http://lists.cs.uiuc.edu/pipermail/cfe-dev/2014-October/039649.html llvm-svn: 220311

This patch adds a new Clang compiler flag "-gline-tables-only". It reduces the amount of emitted debug information: 1) DIEs in .debug_info have types DW_TAG_compile_unit, DW_TAG_subprogram, DW_TAG_inlined_subroutine (for opt builds) and DW_TAG_lexical_block only. 2) .debug_str contains only function names. 3) No debug data for types/namespaces/variables is emitted. 4) The data in .debug_line is enough to produce valid stack traces with function names and line numbers.
