[gdb] Fix heap-use-after-free in typename_concat

When running gdb using AddressSanitizer, and loading a cc1plus binary built
with profiledbootstrap and -flto, we run into a heap-use-after-free error:

This error happens as follows.

The function find_partial_die has a cu argument, but returns a pdi which may
or may not be from that cu:
...
/* Find a partial DIE at OFFSET, which may or may not be in CU,
   except in the case of .debug_types DIEs which do not reference
   outside their CU (they do however referencing other types via
   DW_FORM_ref_sig8).  */

static struct partial_die_info *
find_partial_die (sect_offset sect_off, int offset_in_dwz, struct dwarf2_cu *cu)
...

So the pdi returned by find_partial_die here in partial_die_parent_scope may
be from another cu:
...
partial_die_parent_scope (struct partial_die_info *pdi,
                          struct dwarf2_cu *cu)
{
  const char *grandparent_scope;
  struct partial_die_info *parent, *real_pdi;

  /* We need to look at our parent DIE; if we have a DW_AT_specification,
     then this means the parent of the specification DIE.  */

  real_pdi = pdi;
  while (real_pdi->has_specification)
    real_pdi = find_partial_die (real_pdi->spec_offset,
                                 real_pdi->spec_is_dwz, cu);

  parent = real_pdi->die_parent;
...
in which case both real_pdi and parent will be not from cu, but from another
one, say cu2.

Subsequently, cu's comp_unit_obstack is used to set parent->scope:
...
        parent->scope = typename_concat (&cu->comp_unit_obstack,
                                         grandparent_scope,
                                         parent->name, 0, cu);
...

So, we use cu->comp_unit_obstack to assign a value to the scope field of
a pdi belonging to cu2, and when cu is deleted, the scope field points to a
freed value.

Fix this by making find_partial_die return the cu corresponding to the
returned pdi, and handling this at the call sites.

Tested on x86_64-linux.

Make stap-probe.c:stap_parse_register_operand's "regname" an std::string

This patch simplifies the code of
stap-probe.c:stap_parse_register_operand by making "regname" an
std::string. No functionality change.

I'm this code's maintainer, so I'm pushing this as it's a fairly
trivial patch.

Fix darwin-nat.c build

John Marshall pointed out that darwin-nat.c fails to build:

    CXX    darwin-nat.o
    ../../../binutils-gdb/gdb/darwin-nat.c:1709:8: error: must use 'class' tag to refer to type 'thread_info' in this scope

    Mach has a thread_info() function declared in that header, which darwin-nat.c #includes.

This patch fixes the problem by reintroducing the struct keyword.

Don't crash if dwarf_decode_macro_bytes's 'body' is NULL

Hi,

Ref.: https://bugzilla.redhat.com/show_bug.cgi?id=1708192
      https://bugzilla.redhat.com/show_bug.cgi?id=1708786

During the Fedora RPM build process, gdb-add-index is invoked to
extract the DWARF index from the binary, and GDB will segfault because
dwarf2read.c:parse_definition_macro's 'body' variable is NULL.

The underlying problem is that Fedora's rpm-build's "debugedit"
program will silently corrupt .debug_macro strings when a binary is
compiled with -g3.  This is being taken care of by Mark Wielaard,
here:

  https://bugzilla.redhat.com/show_bug.cgi?id=1708786

However, I still feel it's important to make GDB more resilient
against invalid DWARF input, so I'm proposing this rather simple patch
to catch the situation when "body == NULL" (i.e., it's probably been
corrupted) and issue a complaint.  This is not a real fix to the
problem, of course, but at least GDB is able to finish without
segfaulting.

OK for master?

This adds another test for file numbers given in .file directives,

GDB (s12z): Improve reliability of the stack unwinder.

Previously, the stack unwinder searched through consecutive bytes for values
which it thought might be the start of a stack mutating operation.
This was error prone, because such bytes could also be the operands of other
instructions. This change uses the opcodes api to interpret the code in each
frame.

gdb/ChangeLog:
* s12z-tdep.c (push_pull_get_stack_adjustment): New function.
(advance, posn, abstract_read_memory): New functions.

Fix assertion failure in coerce_unspec_val_to_type

coerce_unspec_val_to_type does:

      set_value_address (result, value_address (val));

However, this is only valid for lval_memory.  This patch changes this
code to only set the address for lval_memory values.

This seems like an ordinary oversight in coerce_unspec_val_to_type,
and a test case would be difficult to write, so I'm submitting it
without a test case.

Tested on x86-64 Fedora 29; plus using an Ada program that exhibits
the bug (but which cannot be shared).

[gdb/testsuite] Fix base address selection entry encoding in dw2-skip-prologue.S

A base address selection entry in a location list consist of two (constant or
relocated) address offsets. The two offsets are the same size as an address
on the target machine.

The test-case gdb.dwarf2/dw2-skip-prologue.S encodes a base address selection
entry using .4byte, which is incorrect for 8-byte pointer size. [ Which
triggers an assert in dwz, see PR dwz/24172. ]

Fix this by using PTRBYTE instead.

Tested on x86_64-linux.

Fix GDB build when using --disable-gdbmi

Since commit

    b4be1b064860 ("Fix MI output for multi-location breakpoints")

we get this error when building with --disable-gdbmi:

      CXXLD  gdb
    /home/smarchi/src/binutils-gdb/gdb/breakpoint.c:6358: error: undefined reference to 'mi_multi_location_breakpoint_output_fixed(ui_out*)'

This is due to breakpoint.c using a function defined in mi/mi-main.c, even
though mi/mi-main.c isn't included in the build.

To fix it, use the flags feature of ui_out.  mi_ui_out has the new
fix_multi_location_breakpoint_output flag set for versions >= 3.  Also,
move the global variable fix_multi_location_breakpoint_output to
breakpoint.c, so it can be read there even when we build without MI.  I
renamed it to fix_multi_location_breakpoint_output_globally so it
doesn't clash with the new enumerator.

gdb/ChangeLog:

* breakpoint.h (fix_multi_location_breakpoint_output_globally):
New variable declaration.
* breakpoint.c (fix_multi_location_breakpoint_output_globally):
New variable.
(print_one_breakpoint): Use ui_out::test_flags and new global

Remove.

fix_multi_location_breakpoint_output flag if version >= 3.
