Fix DWARF FP register numbering on the SPARC

[Eric Botcazou]

This is a follow-up to
  http://gcc.gnu.org/ml/gcc/2009-01/msg00303.html
and removes all traces of DBX_REGISTER_NUMBER from the config/sparc directory, 
thus resetting the default numbering expected by GDB on the SPARC.

Tested by visual inspection on SPARC/Linux and Solaris, applied everywhere.

	* config/sparc/linux.h (DBX_REGISTER_NUMBER): Delete.
	* config/sparc/linux64.h (DBX_REGISTER_NUMBER): Likewise.
	* config/sparc/sysv4.h (DBX_REGISTER_NUMBER): Likewise.
