When debugging diagnostic-show-locus.c, it's invaluable to have a
"ruler" showing column numbers.

This patch adds in support via a new "show_ruler_p" flag within
the diagnostic_context.  There's no direct way for end-users to enable
this, but plugins can enable it by setting the flag, so the
plugin that tests the diagnostic subsystem uses this to verify that
the ruler is correctly printed.

gcc/ChangeLog:
	* diagnostic-show-locus.c (layout::layout): Call show_ruler
	if show_ruler_p was set on the context.
	(layout::show_ruler): New method.
	* diagnostic.h (struct diagnostic_context): Add field
	"show_ruler_p".

gcc/testsuite/ChangeLog:

	(test_very_wide_line): Add ruler to expected output.

Track from which abstract lexical block concrete ones come from in DWARF
so that debuggers can inherit the former from the latter. This enables
debuggers to properly handle the following case:

  * function Child2 is nested in a lexical block, itself nested in
    function Child1;
  * function Child1 is inlined into some call site;
  * function Child2 is never inlined.

Here, Child2 is described in DWARF only in the abstract instance of
Child1. So when debuggers decode Child1's concrete instances, they need
to fetch the definition for Child2 in the corresponding abstract
instance: the DW_AT_abstract_origin link on the lexical block that
embeds Child1 enables them to do that.

Bootstrapped and regtested on x86_64-linux.

gcc/ChangeLog:

	* dwarf2out.c (add_abstract_origin_attribute): Adjust
	documentation comment.  For BLOCK nodes, add a
	DW_AT_abstract_origin attribute that points to the DIE generated

expand_debug_expr handled negative bit positions using:

                else if (bitpos < 0)
                  {
                    HOST_WIDE_INT units
                      = (-bitpos + BITS_PER_UNIT - 1) / BITS_PER_UNIT;
                    op0 = adjust_address_nv (op0, mode1, units);
                    bitpos += units * BITS_PER_UNIT;
                  }

Here "units" is the negative of the (negative) byte offset, so I think
we should be offsetting OP0 by -units instead.  E.g. a bitpos of -17
would give units==3, so this code would move OP0 up by 3 bytes and set
bitpos to 7, giving a total bitpos of 31.

Just noticed by inspection.  An assert triggered for:

        gcc.target/i386/mpx/bitfields-1-lbv.c
        gcc.target/i386/mpx/field-addr-7-lbv.c
        gcc.target/i386/mpx/reference-3-lbv.cpp
        gcc.target/i386/mpx/reference-4-lbv.cpp

at -m32 but otherwise this case doesn't seem to trigger during a
bootstrap and regtest.

Tested on x86_64-linux-gnu.

wide_int_constant_multiple_p used:

          if (*mult_set && mult != 0)
            return false;

to check whether we had previously seen a nonzero multiple, but "mult" is
a pointer to the previous value rather than the previous value itself.

Noticed by inspection while working on another patch, so I don't have a
testcase.  I tried adding an assert for combinations that were wrongly
rejected before but it didn't trigger during a bootstrap and regtest.

Tested on x86_64-linux-gnu.
