Fix regressions introduced by most recent Sparc commits.

Fix regressions introduced by most recent Sparc
commits.
	* config/sparc/sparc.c (output_scc_insn): Enclose || conditions in
	parens while walking over notes.
	* config/sparc/sparc.md (reg movdi split): Clean up matching
	conditions.
	(all DI arithop splits on 32-bit): Handle immediate arguments
	correctly when they are CONST_INTs.
