Brad King 70c2dc8a64 ENH: Make compiler id detection more robust
- Split INFO strings in source into multiple pieces
    to make sure assembly or other listings produced
    by the compiler are never matched by the regex
  - Store INFO strings via pointer instead of array
    to convince some compilers to store the string
    literally in the binary
  - This should help make it work for sdcc 2.8.0 RC1
