Merge lp:~ams-codesourcery/gcc-linaro/merge-4.5-bzr99325-to-4.6 into lp:gcc-linaro/4.6

[Andrew Stubbs]

Merged from Linaro GCC 4.5.

Awaiting upstream review:
  http://gcc.gnu.org/ml/gcc-patches/2011-02/msg00128.html

[Andrew Stubbs (ams-codesourcery)]

I'm going to commit this anyway, without waiting any longer for upstream review. It can always be adjusted later.

review: Approve
