Add nios2 disassembler support. This patch is composed from binutils files
from commit "Opcodes and assembler support for Nios II R2". The files from
binutils used in this patch are:
include/opcode/nios2.h
include/opcode/nios2r1.h
include/opcode/nios2r2.h
opcodes/nios2-opc.c
opcodes/nios2-dis.c
Checkpatch says total: 114 errors, 0 warnings, 3609 lines checked , which
is caused by a different coding style in those files. These warnings and
errors are not addressed To let these files be easily synchronized between
binutils and qemu.

+
+ If pinfo is INSN_MACRO, the mask field stores the macro identifier.
+ Otherwise this is a bit mask for the relevant portions of the opcode
+ when disassembling. If the actual opcode anded with the match field

From: Chris Wulff <crwulff@gmail.com>
Add support for emulating Altera NiosII R1 architecture into qemu.
This patch is based on previous work by Chris Wulff from 2012 and
updated to latest mainline QEMU.

V3: Thorough cleanup, deal with the review comments all over the place
V4: - Use extract32()
- Fix gen_goto_tb() , suppress tcg_gen_goto_tb()
- Clean up gen_check_supervisor() helper
- Use TCGMemOp type for flags
- Drop jump labels from wrctl/rdctl
- More TCG cleanup
V5: - Simplify load/store handling
- Handle loads into R_ZERO from protected page, add comment
V6: - Fix division opcode handling
- Add missing disas handling
- V5 review comments cleanup
V7: - Drop newline at the end of file
V8: - Rebase on top of qemu/master
V9: - Rebase on top of qemu/master
- Init CR_STATUS in nios2_cpu_reset to 0 for start in kernel mode
- Split mmu_read helper into mmu_read_debug helper which produces
MMU debug output only if MMU debugging is enabled and standard
tcg_gen_mov_tl() which facilitates the MMU register read itself.
- Turn MMU settings of the CPU into QoM properties
