[llvm-commits] [PATCH][LNT] Add support for selection of timing statistic (user or real time)

[David Blaikie]

Bump. [5th ping over 2 months]

Any feedback would be appreciated - it's by no means a huge change
(both in size and scope/value) but will hopefully make it a little
easier to investigate other timing properties (& paves the way for
collecting more timing data up into LNT at some point, should anyone
feel there's value in that).
