* Reorganize Travis configuration * Add a `JOB` env var descriptor to all matrix entries. Not used anywhere but is useful when viewing the whole build on Travis's web interface. * Reorganize where builds are located, moving slow builds first and fast ones last. * Change checking the CLI builds from `cargo build` to `cargo check` * Use YAML references to reduce some duplication * Print some more timing statistics for each test * Extract `Project` helper in tests to a module This'll help make it a bit more extensible over time. At the same time the methods are also slightly reorganized to read more clearly from top to bottom. * Migrate all tests away from Webpack Wepback can take a significant amount of time to execute and when it's multiplied by hundreds of tests that adds up really quickly! After investigating Node's `--experimental-modules` option it looks like it's suitable for our use so this switches all tests to using JS files (moving away from TypeScript as well) with `--experimental-modules` with Node. Tests will be selectively re-enabled with webpack and node.js specific output (that doesn't require `--experimental-modules`), coming in later commits. * Restore the node test for node.js output Ensures it's workable as-is * Only generate typescript with webpack * Only read wasm files for webpack * Skip package.json/node_modules for now * Only generate webpack config if needed * Start a dedicated test module for typescript Will hopefully verify the generated Typescript compiles OK. * Remove unneeded `node` method * Fixup some rebase conflicts * Don't run asmjs example on travis * Fixup generator tests * Attempt to fix windows * Comment windows fix * More test fixes * More exclusions * More test fixes * Relax eslint regex Catch mjs modules as well * Fix eslint * Speed up travis on examples slightly
