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.

The X86FixupLEAs pass for Intel Atom must not call
convertToThreeAddress on ADD16rr opcodes, if src1 != src, since that
would cause convertToThreeAddress to try to create a virtual register.
This is not permitted after register allocation, which is when the
X86FixupLEAs pass runs.
This patch fixes PR16785.
Pull in r191715 from upstream llvm trunk:
Forgot to add a break statement.
This should enable building the x11-toolskits/libXaw port with
CPUTYPE=atom.
