[PATCH 0/2] extend opindex and fx_pcrel_adjust to 16 bits

[Dmitry Selyutin <ghostmansd@gmail.com>]

With the upcoming SVP64 extension[0] to PowerPC architecture, it
became evident that PowerPC operand indices no longer fit 8 bits.
These patches extend both the operand index and the dependent
fx_pcrel_adjust field to 16 bits.
This issue has been discussed in binutils mailing list[1]; I've added
gdb-patches mailing list as well, per MAINTAINERS file instructions,
since I'm unsure if this can break the gdb interface.

You can also find these patches in perhaps a more convenient form in
the libresoc fork of binutils repository[2] (branch fx_pcrel_adjust).
