- Upgrade to romcc version 0.63

  This includes more test cases
  Lots of small bug fixes
  A built in C preprocessor
  Initial support for not inlining everything
  __attribute__((noinline)) works
  Better command line options and help
  Constants arrays can be read at compile time
  Asm statements that are not volatile will now be removed when their outputs go unused
  Loads and stores that are not volatile will be removed when their values go unused
  The number of FIXMES in the code is finally starting to go down.
