Merge lp:~uweigand/gcc-linaro/neon-extendsidi-4.7-v3 into lp:gcc-linaro/4.7

[Ulrich Weigand]

Better optimize SI->DI extends that move from core to NEON registers.

2012-09-26: Rebase to neon-shifts-4.7-v3 branch. Add patch to fix regression by making lower-subreg pass less aggressive.
2012-10-01: Disable lower-subreg-1.c test on arm*-*-* instead of just arm-*-*.

Lower-subreg patch posted upstream here:
http://gcc.gnu.org/ml/gcc-patches/2012-09/msg01764.html
and committed to mainline.

Update 2012-12-17: Patch now upstream. OK to backport?

[Ulrich Weigand (uweigand)]

Huh, for some reason the diff linked above is no longer there ...

I'll create a new branch to show a clean diff against current Linaro 4.7 tip of tree.

[Yvan Roux (yvan-roux)]

I think that the link is broken due to the migration in the Lava lab.

Matt just pointed me that launchpad is broken w.r.t. GCC and cannot produce
the diff, I'll checkout your branch and do it on my side.
