Committed my core-shifts patch into Linaro GCC.

Checked and posted my (newly rebased) neon-shifts patch upstream for review.

Continued work on my brain-dump of work in progress. Cleaned up, tested and posted example testcases and before/after compiler output for all my work-in-progress patches.

Looked at LaunchPad bug #851258. It's a miss-optimization bug that would take some effort to fix.

Discovered that my lower-subreg build had failed due to Werror. Fixed the warning, reuploaded the sources, and relaunched the build.

Prepared for travel to Connect.
