[4.9] Switch gcc-4.9 to use google/gcc-4_9 branch.

This source drop uses svn version r212828 of google/gcc-4.9 branch.
We also cherry-picked r213062, r213063 and r213064 to fix windows
build issues.
All gcc-4.9 patches before July 3rd are ported to google/gcc-4.9.
The following prior commits has not been merged to google branch yet.
(They are included in this commit).

-/* __builtin_tbegin has to emit clobbers for all FPRs since the tbegin
-   instruction does not automatically preserves them.  If the
-   transaction body is fully contained in a function the backend tries
-   after reload to get rid of the FPR save/restore operations
-   triggered by the clobbers.  This testcase failed since the backend
-   was able to get rid of all FPR saves/restores and since these were
-   the only stack operations also of the entire stack space.  So even
-   the save/restore of the stack pointer was omitted in the end.
-   However, since the frame layout has been fixed before, the prologue
-   still generated the stack pointer decrement making foo return with
-   a modified stack pointer.  */
