corresponding configure script commit because it doesn't affect
functionality and we don't want to force everyone into another reconfigure

previously temporary NULLCOMP implementation that merely copies the data
verbatim without compression. Also, don't warn if there's no compression
library as that is taken care of during configuration time.

class needs to implement an alternate mechanism based on malloc'd memory
and file reading/writing for platforms without virtual memory.

old and broken AT&T syntax assemblers.  The problem with this hack is that
*SOME* forms of the fdiv and fsub instructions have the 'r' bit inverted.
This was a real pain to figure out, but is trivially easy to support: thus
we are now bug compatible with gas and gcc.

eliminate the GasBugWorkaroundEmitter class, but for now AT&T style emission
is not fully operational.

hopefully lead to the death of the 'GasBugWorkaroundEmitter'.  This also
includes changes to wrap the whole file to 80 columns! Woot! :)

Note that the AT&T style output has not been tested at all.
