Igor Tsimbalist 14e335edc8 CET shouldn't be enabled in 32-bit run-time libraries by defualt 
ENDBR32 and RDSSPD are multi-byte NOPs on x86-64 processors and
newer x86 processors, starting Pentium Pro.  They are UD on older
32-bit processors. Detect this at configure time and adjust the
default value for enable_cet. GCC will enable CET in 32-bit run-time
libraries in any case if --enable-cet is used to configure GCC.

	PR target/84148
	* config/cet.m4: Check if target support multi-byte NOPS (SSE).
	* libatomic/configure: Regenerate.
	* libbacktrace/configure: Likewise.
	* libgcc/configure: Likewise.
	* libgfortran/configure: Likewise.
	* libgomp/configure: Likewise.
	* libitm/configure: Likewise.
	* libmpx/configure: Likewise.
	* libobjc/configure: Likewise.
	* libquadmath/configure: Likewise.
	* libsanitizer/configure: Likewise.
	* libssp/configure: Likewise.
	* libstdc++-v3/configure: Likewise.
	* libvtv/configure: Likewise.

AddressSanitizer (http://code.google.com/p/address-sanitizer) and
ThreadSanitizer (http://code.google.com/p/thread-sanitizer/) are
projects initially developed by Google Inc.
Both tools consist of a compiler module and a run-time library.
The sources of the run-time library for these projects are hosted at
http://llvm.org/svn/llvm-project/compiler-rt in the following directories:
  include/sanitizer
  lib/sanitizer_common
  lib/interception
  lib/asan
  lib/tsan
  lib/lsan
  lib/ubsan

Trivial and urgent fixes (portability, build fixes, etc.) may go directly to the
GCC tree.  All non-trivial changes, functionality improvements, etc. should go
through the upstream tree first and then be merged back to the GCC tree.
The merges from upstream should be done with the aid of the merge.sh script;
it will also update the file MERGE to contain the upstream revision
we merged with.
