ab07951c0c gcc: backport some fixes from llvm-gcc 
llvm-gcc backported some patches from gcc trunk:

http://gcc.gnu.org/ml/gcc-cvs/2007-05/msg00662.html
http://gcc.gnu.org/ml/gcc-cvs/2007-07/msg00019.html
http://gcc.gnu.org/ml/gcc-cvs/2007-08/msg00240.html
http://gcc.gnu.org/ml/gcc-cvs/2007-08/msg00493.html

The first two were always GPL2. The last two were
added after the GPL3 transition, but were written
by aaw@google.com and Rafael Espíndola got permission
to relicense them under the GPL2 for inclusion in
llvm-gcc.

This fixes GCC-PR c++/31749

b078889a6b Revert r259619: 
Fixes GCC libstdc++/29286

The fix seems to work for amd64 but causes segfaults on powerpc.
At this time gcc is much more important on powerpc than on amd64.

cc1a345c65 gcc: revert Rvalue references. 
They are very useful but at this time I prefer not to figure out
some  minor conflicts with the bigger Apple's blocks support
patch that is being worked on for current.

9a252f0990 gcc: Make use of TREE_OVERFLOW_P.

bringing the rest of the change has the advantage of fixing

123906, 125246, and 125721.
