PR description:
As per title, and presented at TRK POG meeting on Feb. 11:
https://indico.cern.ch/event/1498184/#56-mkfit-updates-for-phase-2

As presented at TRK POG meeting on Feb. 11:
https://indico.cern.ch/event/1498184/#56-mkfit-updates-for-phase-2

In short: physics performance is ~ on par with CKF (default), while timing is reduced.

It requires PR cms-data/RecoTracker-MkFit#16 for results shown at TRK POG.

Clang Build

I found compilation warning while trying to compile with clang. Command used:

USER_CUDA_FLAGS='--expt-relaxed-constexpr' USER_CXXFLAGS='-Wno-register -fsyntax-only' /usr/bin/time -v scram build -k -j 32 COMPILER='llvm compile'

See details on the summary page.

I believe the error/warning (https://cmssdt.cern.ch/SDT/jenkins-artifacts/pull-request-integration/PR-571dc6/44467/clang-new-warnings.log) seems fully unrelated to this PR, and I can't reproduce it myself. Should I just try to relaunch the tests? (@cms-sw/operations-l2, @cms-sw/orp-l2)

unless you get a very quiet IB (no merges from an IB to the start of the tests), I think the cms-data part should be merged first and then the tests rerun; otherwise the bot pick up everything from the master in addition to the PR during the tests.

Thanks! I launched the tests for the cms-data PR, and relaunched this too (just in case random errors do not show up).

Tests have passed, for both this and cms-data/RecoTracker-MkFit#16 (analogous results, as it should be). @cms-sw/operations-l2 and @cms-sw/orp-l2, I believe these two are now in your hands. Thanks!

should this be checked by reconstruction as well? A relevant L2 would need to assign.
