rts, base: Refactor stats.c to improve --machine-readable report
There should be no change in the output of the '+RTS -s' (summary)
report, or the 'RTS -t' (one-line) report.
All data shown in the summary report is now shown in the machine
readable report.
All data in RTSStats is now shown in the machine readable report.
init times are added to RTSStats and added to GHC.Stats.
Example of the new output:
