Output DW_AT_entry_pc based on markers.

Introduce DW_AT_GNU_entry_view as a DWARF extension.

If views are enabled are we're not in strict compliance mode, output
DW_AT_GNU_entry_view if it might be nonzero.

This patch depends on SFN and LVU patchsets, and on the IEPM patch that
introduces the inline_entry debug hook.

This patch introduces an option to enable the generation of location
views along with location lists.  The exact format depends on the
DWARF version: it can be a separate attribute (DW_AT_GNU_locviews) or
(DW_LLE_view_pair) entries in DWARF5+ loclists.

Line number tables are also affected.  If the assembler is found, at
compiler build time, to support .loc views, we use them and
assembler-computed view labels, otherwise we output compiler-generated
line number programs with conservatively-computed view labels.  In
either case, we output view information next to line number changes
when verbose assembly output is requested.

This patch requires an LVU patch that modifies the exported API of
final_scan_insn.  It also expects the entire SFN patchset to be
installed first, although SFN is not a requirement for LVU.

Gold plugins may wish to further process an input file added by a plugin. For
example, the plugin may need to assign a unique segment for sections in a
plugin-generated input file. This patch adds a plugin callback that the linker
will call when reading symbols from a new input file added after the
all_symbols_read event (i.e. an input file added by a plugin).

This is a version of the patch posted by Trevor Saunders on 2017-07-31,
for which he wrote:
> For most of the history of this see
>   https://sourceware.org/ml/gdb-patches/2016-10/msg00223.html
> The changes are mostly s/gdb/gtl/g

This version was updated by me (dmalcolm) adding these changes:
- renaming of "gtl" to "gnu" (3 letters, and one of the ones Richi
  proposed, and not a match for "*tl")
- renaming of DEFINE_GDB_UNIQUE_PTR to DEFINE_GNU_UNIQUE_PTR
- renaming of xfree_deleter to xmalloc_deleter, and making it
  use "free" rather than "xfree" (which doesn't exist)
- added a gcc/unique-ptr-tests.cc
- implement unique_xmalloc_ptr<T[]> (taken from gdb, but changing
  "xfree" to "free", and adding support for pre-C++-11)

We have many classes that copy cotr and assignment operator are deleted
in different projects, gcc, gdb and gold.  So this patch adds a macro
to do this, and replace these existing mechanical code with macro
DISABLE_COPY_AND_ASSIGN.

The patch was posted in gdb-patches,
https://sourceware.org/ml/gdb-patches/2017-07/msg00254.html but we
think it is better to put this macro in include/ansidecl.h so that
other projects can use it too.

  A new vendor CFA DW_CFA_AARCH64_negate_ra_state was introduced for ARMv8.3-A
return address signing, it is multiplexing DW_CFA_GNU_window_save in CFA vendor
extension space.

  This patch adds necessary code to make it available to external, the GDB
patch (https://sourceware.org/ml/gdb-patches/2017-08/msg00215.html) is intended
to use it.

  A new DW_CFA_DUP for it is added in dwarf2.def.  The use of DW_CFA_DUP is to
avoid duplicated case value issue when included in libiberty/dwarfnames.

  Native x86 builds OK to make sure no macro expanding errors.

Extend libcc1's with an API for C++ support.

Extend libcc1's C API to distinguish between integral types with the
same width, as in C++.  Likewise for float types.

Export small bits of functionality from the C++ front-end for use in
libcc1.  Add support for the C++ front-end to look up names and
addresses using a libcc1-registered binding oracle.  Add support for
global friends.

Adds Rust symbol demangler. Rust mangles symbols using GNU_V3 style,
adding a hash and various special character subtitutions. This adds
a new rust style to cplus_demangle and adds 3 helper functions
rust_demangle, rust_demangle_sym and rust_is_mangled.

rust-demangle.c was written by David. Mark did the code formatting to
GNU style and integration into the gcc/libiberty build system and
testsuite.
