* config/tc-mips.c (mips_fix_loongson2f, mips_fix_loongson2f_nop,
mips_fix_loongson2f_jump): New variables.
(md_longopts): Add New options -mfix-loongson2f-nop/jump,
-mno-fix-loongson2f-nop/jump.
(md_parse_option): Initialize variables via above options.
(options): New enums for the above options.
(md_begin): Initialize nop_insn from LOONGSON2F_NOP_INSN.
(fix_loongson2f, fix_loongson2f_nop, fix_loongson2f_jump):
New functions.
(append_insn): call fix_loongson2f().
(mips_handle_align): Replace the implicit nops.
* config/tc-mips.h (MAX_MEM_FOR_RS_ALIGN_CODE): Modified
for the new mips_handle_align().
* doc/c-mips.texi: Document the new options.
* gas/mips/loongson-2f-2.s: New test of -mfix-loongson2f-nop.
* gas/mips/loongson-2f-2.d: Likewise.
* gas/mips/loongson-2f-3.s: New test of -mfix-loongson2f-jump.
* gas/mips/loongson-2f-3.d: Likewise.
* gas/mips/mips.exp: Run the new tests.
* opcode/mips.h (LOONGSON2F_NOP_INSN): New macro.
