* generic/tclExecute.c (EvalStatsCmd): change 'evalstats' to

	return data to interp by default, or if given an arg, use that as
	filename to output to (accepts 'stdout' and 'stderr').
	Fix output to print used inst count data.
	* generic/tclCkalloc.c: change TclDumpMemoryInfo sig to allow
	* generic/tclInt.decls: objPtr as well as FILE* as output.
	* generic/tclIntDecls.h:
