Include <new> in gcc/system.h

Similar to bug 212465, lang/gcc5 doesn't compile with recent versions of libc++, because it attempts to redefine abort():

In file included from /usr/work/share/dim/ports/lang/gcc5/work/gcc-5.4.0/gcc/auto-profile.c:25:
In file included from /usr/include/c++/v1/map:446:
/usr/include/c++/v1/functional:1398:2: error: no member named 'fancy_abort' in namespace 'std::__1'; did you mean simply 'fancy_abort'?
        _VSTD::abort();
        ^~~~~~~
/usr/include/c++/v1/__config:383:15: note: expanded from macro '_VSTD'
#define _VSTD std::_LIBCPP_NAMESPACE
              ^

Patch this in the same way as the other gcc ports, by including <new> in gcc/system.h.

Hmm, even that patch is not enough:

        _VSTD::abort();
        ^~~~~~~
/usr/include/c++/v1/__config:383:15: note: expanded from macro '_VSTD'

              ^

extern void fancy_abort (const char *, int, const char *) ATTRIBUTE_NORETURN;
            ^

This probably needs more hacks to get it right.  I wish the gcc authors would stop redefining abort. :(

Fix more system includes in lang/gcc5

This patch adds two more fixes:
* Move inclusion of <map> and <set> to before "system.h" in gcc/auto-profile.c
* Move inclusion of <map> to before "system.h" in gcc/graphite-isl-ast-to-gimple.c

  gcc/system.h, and moving a few includes to before "system.h".

Log:
  Update to the GCC 5.5 release.  This brings more than 250 final bug
  fixes compared to GCC 5.4 and is the last release planned on the GCC 5
  branch which is now closed.

  files/patch-aarch64-support, files/patch-disable-armvhf-config.gcc,
  files/patch-libgcc-config-arm-unwind-arm, and files/patch-x86-64-fix-m16
  all have been merged upstream in between GCC 5.4 and 5.5 and can thus
  be removed; the same is the case for most of files/patch-libc++.

  Finally, the tarball is now compressed using xz instead of bzip2.
