Speed up CQ by 10-20 mins

Project Member Reported by davidjames@chromium.org, Mar 17 2016 
1. Set compilecheck flag on full-compile builders (~15 min speed up)
2. Allocate more DUTs to any bottleneck paladin builders (e.g. stumpy)
3. Turn off rebooting on master-paladin, which doesn't need it (~5 min speed up)
4. Profit with ~10-20 min speedup in CQ and 2x bigger speedup in median patch handling times.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromiumos/chromite/+/6703f0fcad21716b0de99fe81e1bf3c68f446c7f

commit 6703f0fcad21716b0de99fe81e1bf3c68f446c7f

Skip buildimage stage on full-compile builders.

In the CQ we need to (1) test compile and (2) test all the stages after
compile. We have some builders that use prebuilts and some builders that
build from source (the full-compile builders). The full-compile builders
currently skip almost every stage after build-image, because there's
almost nothing to be gained from the extra testing (it's rare that there
will be any differences there.)

Run DetectIrrelevantChanges stages on compilecheck builders.

This allows the compilecheck flag to be used on full-compile builders.
