This patch fixes all of the "easy" cases, and is _nearly_ all the way
to being able to disable useDeprecatedPositionallyEncodedOperands.
There are a small number of trickier cases, which I've split off into
the next (smaller) patch, for ease of review.

While this changes a large number of lines of source code, it produces
no significant changes in the code generated by tablegen, save for
MTVRSAVEv, which was previously encoding the wrong operand.

Also DQForm

X-Form instructions.

XXForm

DSS/DCB Form (actually misnamed X-forms...)

XLForm

XFXForm -- one codegen change, MTVRSAVEv was previously encoding the wrong operand.

XFLForm, XSForm, XOForm

AForm MForm MDForm MDSForm

VAForm Z22Form Z23Form

fixup: VAForm/VNForm

VXForm

PPC10 prefix formats

EVXForm
