binutils: support for the SPARC M8 processor

This patch adds support for the new SPARC M8 processor (implementing OSA
2017) to binutils.

New instructions:

- Dictionary Unpack

  + dictunpack

- Partitioned Compare with shifted result

  + Signed variants:   fpcmp{le,gt,eq,ne}{8,16,32}shl
  + Unsigned variants: fpcmpu{le,gt}{8,16,32}shl

- Partitioned Dual-Equal compared, with shifted result

  + fpcmpde{8,16,32}shl

- Partitioned Unsigned Range Compare, with shifted result

  + fpcmpur{8,16,32}shl

- 64-bit shifts on Floating-Point registers

  + fps{ll,ra,rl}64x

- Misaligned loads and stores

  + ldm{sh,uh,sw,uw,x,ux}
  + ldm{sh,uh,sw,uw,x,ux}a
  + ldmf{s,d}
  + ldmf{s,d}a

  + stm{h,w,x}
  + stm{h,w,x}a
  + stmf{s,d}
  + stmf{s,d}a

- Oracle Numbers

  + on{add,sub,mul,div}

- Reverse Bytes/Bits

  + revbitsb
  + revbytes{h,w,x}

- Run-Length instructions

  + rle_burst
  + rle_length

- New crypto instructions

  + sha3

- Instruction to read the new register %entropy

  + rd %entropy

New Alternate Address Identifiers:

- 0x24, #ASI_CORE_COMMIT_COUNT
- 0x24, #ASI_CORE_SELECT_COUNT
- 0x48, #ASI_ARF_ECC_REG
- 0x53, #ASI_ITLB_PROBE
- 0x58, #ASI_DSFAR
- 0x5a, #ASI_DTLB_PROBE_PRIMARY
- 0x5b, #ASI_DTLB_PROBE_REAL
- 0x64, #ASI_CORE_SELECT_COMMIT_NHT

The new assembler command-line options for selecting the M8 architecture
are:

-Av9m8 or -Asparc6 for 64-bit binaries.
-Av8plusm8 for 32-bit (v8+) binaries.

The corresponding disassembler command-line options are:

-msparc:v9m8 for 64-bit binaries.
-msparc:v8plusm8 for 32-bit (v8+) binaries.

Tested for regressions in the following targets:
sparc-aout sparc-linux sparc-vxworks sparc64-linux
