tcwg-llvm-*: Moving common stuff out

This is an NFC patch that just common things up. I'm making sure that we
only handle URLs and toolchain downloads in a single place, which will
later be very useful when we get Jenkins to ask these scripts to create
the trigger files.

This is the first part of TCWG-1117. Adding the trigger files will be
the second.

I have tested on my box by sourcing the common file and calling the
functions with the right parameters as well as running the scripts
(build/release/test) with the appropriate arguments but with the core
logic actually commented out.

I have some empty tar balls with the right names on dev-01. :)
