tcwg-llvm-build.sh: Add list of projects to consider

As discussed in TCWG-1134, we need a list of projects to checkout if the
branch is master and there is a revision (buildbot and pre-commit base
cases) as well as a branch and no list (for pre-commit patch cases.

The relationship between lists and branches is that having a branch and
not being in the list is ok, but being in the list and not having a
branch is not. This patch addresses that, so that we can create any
number of trigger jobs without worrying about the parameters we pass.

It should either be safe, user error, or the job will bail.

Needs https://review.linaro.org/19777 to work.
