test-release.sh: Add ability to do a test build using the trunk or branches.

[dsanders]

Summary

Adds --test-trunk and '--test-branch BRANCH' that causes the script to export
the trunk or the specified branch. Otherwise the tag specified by -release, -rc,
etc. will be used. The version portion of the package name will be 'test-trunk'
or 'test-$branch' (any forward slashes in the branch name are replaced with
underscores), for example:

clang+llvm-test-branches_release_35-mips-linux-gnu.tar.xz

This is primarily useful for bringing new release packages up to standard
without needing to create and maintain a tag for the purpose.

Update to 3.7 with D10715 applied since there's no 3.7.0rc1 tag yet

Thanks! This seems useful.

I wonder if we could make this simpler by adding just one command-line option, so one could run the script for example like:

./test-relese.sh -svn-path trunk
or
./test-release.sh -svn-path branches/release_37

And that would get baked into the package name. What do you think?

I don't mind merging them into one option. The reason they're separate is merely that this was originally two patches.

'-test-branch trunk' should already work for testing the trunk so it's a fairly minor change.

[dsanders]

Merged -test-branch and -test-trunk into -svn-path

[hans]

Thanks! Looks good to me.

This error message should probably include the $ExportBranch now to be more useful.
