* GCC

Identified the latent bug that's upset my NEON-shifts testing. It turns out the define-insn-and-shift patterns in arm/sync.md have no length attributes set.

Now that the NEON 64-bit shifts appear to be not broken, I've relaunched the 64-bit extend testing.

Identified the problem with my NEON-64-bit-negate patch: I already knew it works better (produces more optimal code) with my NEON-immediates patch, but it turns out that at -O0 the other patch is a hard requirement or else bad things happen in output_move_vfp.

Backported Ramana's patch for ARM-mode testing of my recent Thumb 64-bit test cases. I've applied it to Linaro GCC directly, without a merge proposal, as it's a very low-risk patch.

Caught up with some launchpad blueprint fiddling.

Completed the merges from 4.6 and 4.7 FSF. The 4.7 merge was tricky as it required working around a BZR bug; I've posted the workaround to the toolchain list.

Attached a copy of the ARM Linux ABI document to KBentry 39 so we're hosting it somewhere, at least. Posted an internal Mentor/CS question about getting its old home restored, and getting a relicensed edition to allow others to use it as the basis for a hard-float equivalent.
