s390.opt ("mhard-float", [...]): Bit value inverted and documentation adjusted. 

2007-03-19  Andreas Krebbel  <krebbel1@de.ibm.com>

	* config/s390/s390.opt ("mhard-float", "msoft-float"): Bit value
	inverted and documentation adjusted.
	("mhard-dfp", "msoft-dfp"): New options.
	* config/s390/s390.c (s390_handle_arch_option): New architecture
	switch: z9-ec.
	(override_options): Sanity checks for the new options added.
	* config.gcc: New architecture switch: z9-ec.
	* config/s390/s390.h (processor_flags): PF_DFP added.
	(TARGET_CPU_DFP, TARGET_DFP): Macro definitions added.
	(TARGET_DEFAULT): Due to the s390.opt changes hard float is enabled
	when the bit is NOT set so remove it from the defaults.
