This patchseries starts in on the job of converting the Arm
Neon decoder to decodetree.
Neon insns come in three major parts:
* the 'v8.0-and-later' extensions
* the 'loads and stores' group
* the 'data processing' group
This patchset converts all of the v8.0-and-later extensions
and the loads-and-stores, plus the "3-registers-same" subgroup
of the data-processing insns.
I'm working on the rest of the dp insns, but this seems like
a pretty large chunk of conversion patches to start with.
thanks
