* Linaro GCC

Applied my ARM conditional-execution and thumb 16-bit instruction size 
optimization patch to upstream and Linaro 4.7.

Continued work on (slowly) working the bugs out of my 64-bit NEON 
patches. Figuring out bootstrap failures is not easy! Eventually 
discovered that:

   * the NEON shifts patch was broken because combine was using the 
patterns in ways they weren't intended.

   * the NEON neg patch was broken because it needed an early-clobber 
marker on the scratch register.

I've also reworked the use of insn_enabled to make it a little less 
clunky. It's just an aesthetic change though.

If all goes well with my weekend bootstrap builds I should have the 
patches reposted next week.



* Other

Richard Earnshaw asked me to bless use of a CS patch submitted to 
gcc-patches@ by a third party. I dug out the original patch from the CS 
archives and posted that to the message thread.
