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.

Unfortunately this causes ICE on powerpc and sparc64.
Reducing these differences against upstream is not important
anymore so hopefully I have finished breaking the compiler
occasionally.
Bring The following revisions from the gcc43 branch[1]:
118360, 118361, 118363, 118576, 119820,
123906, 125246, and 125721.
They all have in common that the were merged long ago
into Apple's gcc and should help improve the general
quality of the compiler and make it easier to bring
new features from Apple's gcc42.
