[PATCH v5 0/7] ppc/svp64: support SVP64 and its first insns

[Dmitry Selyutin]

These patches add support for LibreSOC machine and SVP64 extension flag
for PowerPC architecture. SV (Simple-V) is a strict RISC-paradigm
Scalable Vector Extension for the Power ISA. SVP64 is the 64-bit
Prefixed instruction format implementing SV. Funded by NLnet through EU
Grants No: 825310 and 825322, SV is in DRAFT form and is to be publicly
submitted via the OpenPOWER Foundation ISA Working Group via the
newly-created External RFC Process.

Changes since v4:
- Introduced svindex instruction along with SVI form.
- Fixed svstep test so that ranges for operand 0 are correct.
- Updated commit messages with the links to instructions.
- Renamed SVRMf field to SVrm.

Changes since v3:
- Applied the correct version of patches.

Changes since v2:
- All patches now have the description including links to docs.
- A new operand flag is introduced for ranges 1..n instead of 0..n-1.
- All tests are rewritten for simplicity's sake.

Changes since v1:
- Aliased instruction fields now appear after the original ones.
