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.

* ansidecl.h (DISABLE_COPY_AND_ASSIGN): New macro.
Co-Authored-By: Pedro Alves <palves@redhat.com>
From-SVN: r252823
So that GDB and other projects that share the top level can use them.
Bootstrapped with all default languages + jit on x86-64 Fedora 23.

* coretypes.h (OVERRIDE, FINAL): Delete, moved to
include/ansidecl.h.

Fix PR65261
Running bootstrap-ubsan on ppc64le shows many instances of:
libcpp/lex.c:552:30: runtime error: load of misaligned address
0x01001f31d37a for type 'const uchar', which requires 16 byte alignment
But the unaligned vector loads are intended in this case, because they
are preferable to forced-alignment on POWER8. So just silence the ubsan
errors.
