arc: Add disassembler helper

Add disassembler helper for GDB, that uses opcodes structure arc_instruction
and adds convenience functions to handle instruction operands.  This interface
solves at least those problems with arc_instruction:

  * Some instructions, like "push_s", have implicit operands which are not
    directly present in arc_instruction.
  * Operands of particular meaning, like branch/jump targets, have various
    locations and meaning depending on type of branch/target.
  * Access to operand value is abstracted into a separate function, so callee
    code shouldn't bother if operand value is an immediate value or in a
    register.

Testcases included in this commit are fairly limited - they test exclusively
branch instructions, something that will be used in software single stepping.

Remove lwp -> pid conversion in linux_nat_xfer_partial

The linux_nat_xfer_partial does a conversion of inferior_ptid: if it's
an LWP (ptid::lwp != 0), it builds a new ptid with the lwp as
the pid and assigns that temporarily to inferior_ptid.  For example, if
inferior_ptid is:

  { .pid = 1234, .lwp = 1235 }

it will assign this to inferior_ptid for the duration of the call:

  { .pid = 1235, .lwp = 0 }

Instead of doing this, this patch teaches the inf-ptrace implementation
of xfer_partial to deal with ptids representing lwps by using
get_ptrace_pid.

Also, in linux_proc_xfer_spu and linux_proc_xfer_partial, we use ptid_get_lwp
instead of ptid_get_pid.  While not strictly necessary, since the content of
/proc/<pid> and /proc/<lwp> should be the same, it's a bit safer, because:

- some files under /proc/<pid>/ may not work if the <pid> thread is
  running, just like ptrace requires a stopped thread.  The current
  thread's lwp id is more likely to be in the necessary state (stopped).

- if the leader (<pid>) had exited and is thus now zombie, then several
  files under "/proc/<pid>" won't work, while they will if you use
  "/proc/<lwp>".

Add rvalue references to overloading resolution

This patch introduces changes to rank_one_type() dealing with ranking an rvalue
reference type when selecting a best viable function from a set of candidate
functions. The 4 new added rules for rvalue references are:

1) An rvalue argument cannot be bound to a non-const lvalue reference parameter
and an lvalue argument cannot be bound to an rvalue reference parameter.
[C++11 13.3.3.1.4p3]

2) If a conversion to one type of reference is an identity conversion, and a
conversion to the second type of reference is a non-identity conversion, choose
the first type. [C++11 13.3.3.2p3]

3) An rvalue should be first tried to bind to an rvalue reference, and then to
an lvalue reference. [C++11 13.3.3.2p3]

4) An lvalue reference to a function gets higher priority than an rvalue
reference to a function. [C++11 13.3.3.2p3]

readelf: Don't error on .debug files with NOBITS .dynamic section.

The fix for PR binutils/17512 added a check for the dynamic segment being
inside the actual ELF file. If not an error message would be produced:

readelf: Error: the dynamic segment offset + size exceeds the size of the file

Unfortunately for separate debuginfo files it is common for the dynamic
segment not being inside the file because the .dynamic section is NOBITS.

Since the check is done unconditionally in process_program_headers and
process_program_headers is always called (to setup dynamic_addr in case
it is needed). The error is produced on any operations done on any .debug
file (even if no program headers or the dynamic segment is used).

If there are section headers then a cross check is done to see if the
.dynamic section is NOBITS in which case dynamic_addr is set to zero
without a warning or error (which is then checked first before any
operation on the dynamic segement is done).

Move the check for the dynamic segment being inside the actual ELF file
after the cross check with the section headers to suppress the error for
.debug files.

relative branch instructions, such as cij (compare immediate and branch
relative).  When setting a breakpoint on such an instruction and

against, this patch just treats relative branches and non-branching
