Add missing objects to build-js.sh

[pepyakin]

Added missing symbols which have triggered following warnings during executing build-js.sh:

warning: unresolved symbol: _ZN4wasm10LocalGraph17computeInfluencesEv
warning: unresolved symbol: _ZN4wasm23createConstHoistingPassEv
warning: unresolved symbol: _ZN4wasm10LocalGraphC1EPNS_8FunctionEPNS_6ModuleE

Travis-CI failure looks like it is spurious.

The command "sudo -E apt-get -yq --no-install-suggests --no-install-recommends --force-yes install cmake g++-5" failed and exited with 100 during .

Thanks!

Maybe at some point we should automate these builds in travis. It's too slow though, it more than doubles the build times...
