all of the features in the current working draft of the upcoming C++
standard, provisionally named C++1y.
The code generator's performance is greatly increased, and the loop
auto-vectorizer is now enabled at -Os and -O2 in addition to -O3. The
PowerPC backend has made several major improvements to code generation
quality and compile time, and the X86, SPARC, ARM32, Aarch64 and SystemZ
backends have all seen major feature work.

Don't use nopl in cpus that don't support it.
Patch by Mikulas Patocka. I added the test. I checked that for cpu names that
gas knows about, it also doesn't generate nopl.
The modified cpus:
i686 - there are i686-class CPUs that don't have nopl: Via c3, Transmeta
Crusoe, Microsoft VirtualBox - see
https://bbs.archlinux.org/viewtopic.php?pid=775414
k6, k6-2, k6-3, winchip-c6, winchip2 - these are 586-class CPUs
via c3 c3-2 - see https://bugs.archlinux.org/task/19733 as a proof that
Via c3 and c3-Nehemiah don't have nopl

X86: Disable long nops for all cpus prior to pentiumpro/i686.
This is the safest approach for now. If you think long nops matter a
lot for performance, compile with -march=i686 or higher. :)

When creating MCAsmBackend pass the CPU string as well. In X86AsmBackend
store this and use it to not emit long nops when the CPU is geode which
doesnt support them.
Fixes PR11212.
Pull in r164133 from upstream clang trunk:
Follow up on llvm r164132.
This should prevent illegal instructions when building world on Geode
CPUs (e.g. Soekris).
