Just to clarify, that seems perfectly fine for the "machine readable"
output formats. I'd just like fewer lines in the "human readable"
output.

That's going in the right direction. Personally I'd make the last line
more like
Times: generation 0.680 ms, inlining 7.591 ms, optimization 20.522 ms, emission 14.607 ms, total 43.4 ms
(total at the end seems more natural to me, YMMV). Also, the "options"
format you suggest here seems a bit too biased towards binary on/off
options --- what happens when there's a three-way option? So maybe that
line should be like
Options: inlining on, optimization on
though I'm less sure about that part.
