tools/perf: Map the ID values with register names
Map ID values with corresponding register names. These names are then
displayed when user issues perf record with the -I option
followed by perf report/script with -D option.
To test this patchset, Eg:
$ perf record -I ls # record machine state at interrupt
$ perf script -D # read the perf.data file
Sample output obtained for this patch / output looks like as follows:
