Tweaks to compile against latest analyzer.  Also changes the travis
setup to only override analyzer dependencies when $ANALYZER is
explicitly set to master.

File .travis.yml (right):

https://codereview.chromium.org/1808123006/diff/1/.travis.yml#newcode11
.travis.yml:11: - test "$ANALYZER" != master ||
./tool/override_analyzer_dependency.sh
The previous test fired the dependency override when $ANALYZER was not set,
which I don't think was intended.

LGTM! Nice to see the code in DDC get smaller with the Coercion clean up too.
