Chris Lattner 837caa7223 Comment out debug code :) 
Select [mem] += Val operations.  For constants, we used to get:

  mov %ECX, -32768
  add %ECX, DWORD PTR [l4_match_start]
  mov DWORD PTR [l4_match_start], %ECX

Now we get:

  add DWORD PTR [l4_match_start], -32768

For other values we used to get:

  mov %EBP, %EDI   ;; because the add destroys the value
  add %EBP, DWORD PTR [l4_input_len]
  mov DWORD PTR [l4_input_len], %EBP

now we get:

  add DWORD PTR [l4_input_len], %EDI

Both of these use less registers than the alternative, are faster and smaller.
