perf annotate: Set instruction name to be used with insn-stat when using raw instruction

Since the "ins.name" is not set while using raw instruction,
'perf annotate' with insn-stat gives wrong data:

Result from "./perf annotate --data-type --insn-stat":

  Annotate Instruction stats
  total 615, ok 419 (68.1%), bad 196 (31.9%)

    Name      :  Good   Bad
    -----------------------------------------------------------
              :   419   196

This patch sets "dl->ins.name" in arch specific function
"check_ppc_insn" while initialising "struct disasm_line".

Also update "ins_find" function to pass "struct disasm_line" as a
parameter so as to set its name field in arch specific call.

With the patch changes:
