[linaro/gcc-4_8-branch] Merge from upstream gcc-4_8-branch and backports from trunk

[Matthew Gretton-Dann]

Hi,

I have just merge upstream gcc-4_8-branch into linaro/gcc-4_8-branch, up to 
r197294.  (The merge is r197598.)

I have also backported the following trunk revisions into the 
linaro/gcc-4_8-branch: 196856, 196858, 196876, 197046, 197051, 197052, 
197153, 197207, 197341, 197342, and 197346. (Backports are revisions 
197599:197609).

Thanks,

Matt
