ART: X86Mir2Lir::OpRegRegReg should expect kOpMul for r_dest == r_src2 case

OpRegRegReg in case of r_dest == r_src2 does not expect kOpMul as valid operation.
This provokes abort compiling instruction like "mul-int v0, v1, v0" if both
operands are arriving in registers.

The fix is to expect kOpMul as comutative operation.
