sched-vis.c (print_exp): Handle FMA explicitly.

Browse Source 
* sched-vis.c (print_exp): Handle FMA explicitly.  Simplify handling
	of RTX_UNARY function-like operations.  Print unknown expression
	RTX classes as pseudo-functions.
	(print_pattern): Simplify return pattern printing.
	(dump_insn_slim): Print the value of notes as a pattern for proper
	printing of CFA notes.
