Cleanup some the downloaded ARM target algorithm code:

 - Provide more complete disassembly of the DCC bulk write code

 - Make code blocks "static const", in case GCC doesn't

 - Fix some tabbing/layout issues

 - Make some arm7_9_common.h flags be "bool" not "int"; and compact
   the layout a bit (group most bools together)
