DWARF: fix stack usage assessment for DW_OP_neg

When the DWARF back-end generates DW_OP_neg operations in DWARF
procedures, we get an ICE because of inconsistent stack usage
computation for the embedding expression. This is because
resolve_args_picking_1 thinks DW_OP_neg is a binary operation (pops 2
stack slots, pushes 1) whereas it really is an unary one (one pop, one
push).

This change fixes resolve_args_picking_1 and adds a regression testcase
(which crashes with the current trunk).  Bootstrapped and regtested

Add debugging ruler to diagnostic-show-locus.c

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.

DWARF: add abstract origin links on lexical blocks DIEs

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.

Fix handling of negative bitpos in expand_debug_expr

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
