Execute permissions are needed on the wasm_exec.js file but nothing seems to set this by default. Once set, it will keep permissions even after rebuilds, but this change will set the initial permissions if required for any new environments.

We are not using the benchmark results for anything, they are mostly
there to ensure that we don't break the benchmarks. So we can disable
CockroachDB for them.
Similarly add short versions of other tests.
Also try to precompile test/benchmark code.
