Eliminate the need for an intermediate array of indices into the arrays of

interrupt counts and names, by making the names into an array of fixed-length
strings that can be directly indexed.  This eliminates extra memory accesses
on every interrupt to increment the counts.

As a side effect, it also fixes a bug that would corrupt the names data
if a name was longer than MAXCOMLEN, which led to incorrect vmstat -i output.
