[Qemu-devel] [RFC v2 00/13] POWER9 TCG enablements - part1

[Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>]

This set starts adding new instructions for POWER9 described in ISA3.0.

Patches:
  01-02: First two patches adds the required POWER9 cpu model and ISA defines.
  03-12: Adds following instructions:
             addpcis   : Add PC Immediate Shifted
             cmprb     : Compare Ranged Byte
             moduw     : Modulo Unsigned Word
             modsw     : Modulo Signed Word
             modud     : Modulo Unsigned Dword
             modsd     : Modulo Signed Dword
             cnttzd[.] : Count Trailing Zero Dword
             cnttzw[.] : Count Trailing Zero Word
             cmpeqb    : Compare Equal Byte
             setb      : Set Boolean
             maddld    : Multiply-Add Low Dword
             maddhd    : Multiply-Add High Dword
             maddhdu   : Multiply-Add High Dword Unsigned
     13: Adds support for the new Expanded Opcode (EO) added in ISA3.0

Thanks to Richard, David and Bharata for their valuable feedback.

Changelog:
v1:
* addpcis - shift the immediate before adding
* cmprb logic without branches
* mod[su][wd]: use helpers
* cmpeqb - use bit magics in the helpers
* setb - bug fix and branchless
* maddld - discard multiple dword calculation as we need only lower 64-bit
* Expanded opcode - drop pad from 32-bit and free the third level indirect 
  table in unrealize
