Another minor tweak to the SPARC back-end

[Eric Botcazou]

I've always found UNSPEC_GET_PC and get_pc to be poorly evocative.  Also the 
pattern could be reused for something else than loading the PIC register.

Bootstrapped/regtested on sparc64-sun-solaris2.9 and sparc-sun-solaris2.8.

Applied to mainline.

	* config/sparc/sparc.c (get_pc_symbol): Rename into
	add_pc_to_pic_symbol.
	(get_pc_symbol_name): Rename into add_pc_to_pic_symbol_name.
	(load_pic_register): Account for previous changes.
	Use reg_names.  Don't create the label twice.
	* config/sparc/sparc.md (UNSPEC_GET_PC): Rename into
	UNSPEC_LOAD_PCREL_SYM.
	(get_pc): Rename into load_pcrel_sym.  Add predicate to
	operands.  Remove condition.
