[PATCH 0/1] ppc: support register names in macros

[Dmitry Selyutin]

This patch is a follow-up of discussion:

https://sourceware.org/pipermail/binutils/2022-July/121719.html

Form now on, PPC assembly becomes capable of compiling such code:

    .set VREG, %r0
    .set REG, VREG
    extsw REG, 2  
    extsw %r1, 1

The custom register_name() code path, as well as checks for CRs, are
deprecated; from now on, we use md_operand() routine everywhere.

Whilst we're here, let's also reuse register lookup for CFI.
