  * This assembler uses the following register assignment convention
  * - r5 : Pointer to current code object (Code*) including heap object tag.
  * - r6 : Current position in input, as negative offset from end of string.
  *        Please notice that this is the byte offset, not the character offset!
  * - r7 : Currently loaded character. Must be loaded using
  *        LoadCurrentCharacter before using any of the dispatch methods.
  * - r8 : points to tip of backtrack stack
  * - r9 : Unused, might be used by C code and expected unchanged.
  * - r10 : End of input (points to byte after last character in input).
