Remerged the GCC 4.7 branch from upstream. I had previously misunderstood how to resolve a conflict where Uli had committed a different version of the same patch upstream.

Spun the GCC 4.6 and 4.7 release tarballs and passed them to Michael for testing.

Continued work on improving code generation for 64-bit and/or/not/xor. I now have this working to the point where it would be ready to post upstream .... except that it depends on my other patches that are not yet committed (or even reviewed) upstream.

Rebased and modified my core-shifts patch following Ramana's code review. Then regression tested it - no regressions - and committed the patch upstream. I've also updated the launchpad branch and resubmitted the merge request with the finalized upstream patch.

Rebased the neon-shifts patch. I'll repost this upstream as soon as I'm happy it still works correctly.

Worked on a brain-dump of all I have been working on recently. This will hopefully help others take over my tasks after the contract expires. I still need to put together all the test-cases and examples that Ramana requested.
