Implement METHOD STATS verbose output

[gita-omr]

• introduce new verbose tag: "#METHOD STATS"
• print "key=value" pairs for each method where "key" is an arbitrary string
• values can be agrregated across all methods by a parsing script
• this format can be used for an arbitrary info about a compiled method
• in particular, introduce a function that prints various footprint
  stats for a method
