Added more instructions to opcode table

BEQ, BIT, BMI, BNE,BPL,BRA,BRK,BVC,BVS,CLC,CLD,CLI,CLV,CMP,CPX were all
added in this commit.

NOTE: I have stopped placing in negative test cases to test all of the
      invalid addressing modes for each instruction.  I will make up
      for this missing coverage in the future by performing a full
      compare of the opcode table in this function to snaps 65c02
      table.  A lof of the negative test cases were already covered in
      the more thorough test instructions leading up to this commit.
